To make a sortable table, add the sortable
class to a table.
This class adds arrows displayed beside the header within each header cell.
When you click on an arrow, the table rows are arranged according to the chosen column.
Continuously clicking the arrow alters the sorting order in the following pattern: Ascending, Descending, and then Unsorted.
You can perform secondary sorts by shift-clicking the arrows in different columns.
Each shift click will set the secondary sort based on the clicked column, and this capability extends to tertiary and further sorts.
Sort modes
Items are sorted based on the data type of the first few rows below the header. To determine the data type, the first five non-empty rows below the header are examined upon page loading, and the most suitable format is selected. Discrepancies can occur. Additionally, specific columns can have their sorting order forced, as explained in the relevant section below.
Currently, tags like span or sup don't affect how data types are determined, but reference numbers and visible comments do.
Dates
Different date formats are accepted, even those with month names in local languages. For instance, on the German Wikipedia, "16. März 2010" is appropriately sorted as 2010-03-16.
Different numerical formats, including ones with various separators like periods, commas, apostrophes, or slashes (such as . , ' /
), are supported.
The English Wikipedia typically uses the US date format, (e.g. month-day-year).
Numbers
The script can detect numbers that use either "." or "," as decimal separators, as well as numbers written in scientific notation (using "e" or "E"). By default, numbers will be sorted based on alphanumeric order by default, meaning that they will be sorted as strings rather than numerical values. This may result in unexpected sortings, such as "9" coming after "10". However, this default behavior can be overridden if desired.
Text
When lists are sorted alphabetically by MediaWiki, the order of characters is sorted with Intl.Collator
.
This sorts accented characters correctly based on PageContentLanguage
.
Android Webviews don't support this, so fallback to the old sort routine is required. The order is the same as the order of Unicode code points. Some of the more common characters are ordered as follows (in ascending order):
! | " | # | $ | % | & | ' | ( | ) | * | + | , | - | . | / | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | : | ; | < | = | > | ? | @ | A | B | C | |

Forcing the sort mode of a column
Adding data-sort-type="..."
to the header lets you control how a table is sorted.
This feature is derived from tablesorter.com (webarchive).
Valid values for "data-sort-type" include the following which are not case-sensitive:
- currency
- number
- isoDate
- time
- IPAddress
- usLongDate
- date
- text
- url
For example:
Wikitext
{|class="wikitable sortable" !data-sort-type="date"| Date !! Name !! Height !!data-sort-type="number"| Salary |- | 01.10.1977 || Smith || 1.85 || 1,000.000 |- | 11.6.1972 || Ray || 1.89 || 900.000 |- | 1.9.1992 || Bianchi || 1.72 || 2,000.50 |}
Rendering
Date | Name | Height | Salary |
---|---|---|---|

11.6.1972 | Ray | 1.89 | 900.000 |
1.9.1992 | Bianchi | 1.72 | 2,000.50 |
Specifying a sort key
You can adjust how cells are sorted or parsed if needed.
For instance, if a cell says "John Smith" but should be sorted under "Smith", you can use the data-sort-value="..."
attribute to achieve this.
Wikitext
{|class="wikitable sortable" ! Name and Surname !! Height |- |data-sort-value="Smith, John"| John Smith || 1.85 |- |data-sort-value="Ray, Ian"| Ian Ray || 1.89 |- |data-sort-value="Bianchi, Zachary"| Zachary Bianchi || 1.72 |}
Rendering
Name and Surname | Height |
---|---|
John Smith | 1.85 |
Ian Ray | 1.89 |
Zachary Bianchi | 1.72 |
Controlling sorting and display
To ensure certain text isn't sorted but still displayed, use data-sort-type="..."
.
You can then append additional text after values, like "200 approx" or "100<sup style="color:blue" title="link to Reference">[1]".
An empty cell sorts as "-Infinity"
.
If a cell contains a range of dates or numbers (for example, from 2 to 5), use data-sort-value="..."
.
Examples
The first column sorts plain numbers.
The second column sorts more content as numbers using data-sort-type="number"
in the table header.
The fourth column defines numeric sort values independently of cell content using data-sort-value="..."
.
numbers | data-sort-type="number" |
data-sort-type="number"
| |
---|---|---|---|
-8e3 | -8 e3 | -8 e3 | |
-3e-3 | -3 e-3 | -3 e-3 | |
2.000 | 2-5 km² | data-sort-value="3.5" |
2-5 km² |
3.99 | 3.99 km² | 3.99 km² | |
4 | 4 km² | 4 km² | |
90 % | 90 Percent | data-sort-value="90" |
about 90 Percent |
1E2 | 100[1] | 100[1] | |
1,000,000.0 | 1 000 000.0 | data-sort-value="1e6" |
one Million |
The way commas (,) and decimal points (.) are displayed in Mediawiki depends on the language settings. Currency symbols and the percentage (%) symbol are sorted numerically based on these settings.

Secondary sort key
You can sort data by columns, with Column A as the primary sort key. If Column A has equal values, use Column B as the secondary key. Click Column A's sort button once or twice, then while holding shift, click Column B's sort button once or twice for further refinement.
For example:
Click on the "Text" column first, then hold down the shift key and click on the "Numbers" column. You'll notice that the items are sorted based on text first and then numbers.
Numbers | Text | Dates | Currency | More text |
---|---|---|---|---|
4 | a | 01.Jan.2005 | 4.20 | row 1 |
5 | a | 05/12/2006 | 7.15 | row 2 |

Additional features
Excluding the last row from sorting
You can skip sorting the last row of a table by marking it with class="sortbottom"
.
You can also exclude it from sorting by declaring it as a footer with an exclamation mark (!
).

Making a column unsortable
To stop a column from being sortable, use class="unsortable"
in its header cell's attributes.

Keeping some rows together
To allow an uncolumned row to always stay beneath the columned row above it, no matter how you sort them, use class="expand-child"
in the row's attribute.
Wikitext
{| class="wikitable sortable" !style="width:9em"| Country !!data-sort-type="number"| Area |- | France | 674 843 km² |- class="expand-child" style="font-size:85%; line-height:1.2; color:gray" |colspan="2"| In Paris is the Eiffel Tower. |- | U.K. | 242 495 km² |- class="expand-child" style="font-size:85%; line-height:1.2; color:gray" |colspan="2"| In the U.K. you cannot pay with euros. |- class="expand-child" style="font-size:85%; line-height:1.2; color:gray" |colspan="2"| And you drive on the left side of the road. |- | Germany | 357 168 km² |- class="expand-child" style="font-size:85%; line-height:1.2; color:gray" |colspan="2"| Germany includes the former DDR. |}
Rendering
Country | Area |
---|---|
France | 674 843 km² |
In Paris is the Eiffel Tower. | |
U.K. | 242 495 km² |
In the U.K. you cannot pay with euros. | |
And you drive on the left side of the road. | |
Germany | 357 168 km² |
Germany includes the former DDR. |
If you put in data-sort-value
the same content as above row, keep this rows also together.
The original mutual order of these rows is preserved.
A better way for this is class expand-child, see above #Keeping some rows together.
Example where data-sort-value
is used is the case for the rows about the Netherlands:
{|class="wikitable sortable"
! Country/province !! Capital
|-
| France || Paris
|-
| Netherlands || Amsterdam
|-
|data-sort-value="Netherlands"| South Holland ||data-sort-value="Amsterdam"| The Hague
|-
| U.K. || London
|}
Country/province | Capital |
---|---|
France | Paris |
Netherlands | Amsterdam |
South Holland | The Hague |
U.K. | London |
Special dates
To represent years Before Christ (BC) subtract the BC year from 10,000. For instance, -62 BC would be 10,000 - 62 = 9938.
For example, September 23, 62 BC would be represented as 9938-09-23.
If a table column has incomplete dates, sorting won't be an issue. If only a year and month are provided, it's sorted before the first day of that month. Similarly, if only a year is given, it's sorted before the first month or day of that year.

Using #time
You can use the parser function #time and HTML tags to display a specific date range.
By adding the HTML tag <span style="display:none">&{{#expr:3e11+{{#time:U|..}}}}</span>
before the displayed date, you can manipulate the way the date is shown.
This method works for dates between January 1, 111 CE, and December 31, 9999 CE, using the proleptic Gregorian calendar.
The added value ensures all values are positive and uniform in length.
Placing "&" before the expression forces string sorting mode.
You can input dates and times using any PHP format for date and time. Remember, if you're specifying just a year, you must include a month (usually January) in the background.
For example using date :
input date | text | date and time as interpreted, with hidden sort key | input with visible sort key | input with hidden sort key | Unix time |

To use dates before 111 AD, add a multiple of 400 (like 6000) to all years. This shifts the range to start from January 1st, -5889, aat 00:00:00, and ends on December 31st, 3999, at 23:59:59, without altering the calendar system.

Cell spanning multiple rows/cells
A cell that extends across multiple rows or columns is considered equivalent to having multiple cells with identical values.

Any missing cells at the end of a row will turn into empty cells after the first sort.
Colspanned cells
Sort modes are detected separately for each column containing colspanned cells.
You can set a sort mode for all colspanned columns by including data-sort-type
in the header.
To implement separate sort keys for each column within a colspanned cell, utilize a CSS trick described here: Ensure an equal number of cells in each row for sortable columns. If there's a mismatch, all columns become sortable. This rule should apply up to and including the last sortable column. However, employing a CSS workaround allows for a difference between the displayed number of cells in a row and the formal count. For instance, two formal cells can appear as one by adjusting the width of the first column, shifting the content of the second cell to the left, increasing its width by the same measure, and concealing the cell border that would typically be visible. Concealed sort keys enable managing the sorting order of specific rows in relation to each column.
For example:
Country | Capital |
---|---|
France | Paris |
U.K. | London |
Static column
To make a static column, like one with row numbers, use two tables placed next to each other. Make sure each row in both tables has the same height. You can also use w:Template:Static row numbers to generate row numbers implicitly using CSS rather than creating another table.

The formatting can be modified to present everything in a unified table. If a row is too short for the text in a cell, the browser will expand it, disrupting the alignment.
Default order
You can't show a table sorted by a column without the user clicking on it. By default, table rows appear in the order as the wikitext. To display a table sorted by a specific column, you'll need to arrange the wikitext accordingly. One way of doing this is:
- Rearrange the table's wikitext without the top and bottom lines.
- Replace the cell separators with a unique code that doesn't contain a "|" by using "find and replace".
- Replace any pipes within table cells with a code, and then substitute that code with a newline character preceded by it (indicating the start of a new row).
- Use the Sort module on Special:ExpandTemplates. To sort the items between the pipes and produce the desired separator, expand templates and add
{{#invoke:Sort|f||- |
(with the newline) before and}}
after the wikitext. - Delete the items that begin with "-" and a newline.
- Change the temporary codes for the cell separators and pipes inside the cells to restore them.
This sorting method relies on the wikitext in each row, primarily sorting by the content of the first column. The second column serves as a secondary key. However, wikitext codes in the first column cells before the content can impact the order.
You can also use Snippets/Sort table on reload to automatically sort the table when it loads using JavaScript.
Persistent sort states using cookies
You can save the state of sortable tables across reloads using Snippets/Persistent sort order .
