As tabelas podem ser criadas em páginas wiki. Como regra geral, é aconselhável evitar o uso de tabelas, a menos que seja realmente necessário. A marcação de tabelas geralmente dificulta a edição de páginas.

Resumo dos elementos wiki de construção de tabelas

 * Os elementos de construção de tabelas têm de começar numa linha nova, exceto os sinais duplos e  para opcionalmente adicionar elementos consecutivos numa só linha. No entanto, espaços em branco no início da linha são ignorados.
 * Atributos HTML. Cada elemento, exceto o final da tabela, opcionalmente aceita um ou mais atributos HTML. Os atributos têm de estar na mesma linha que o elemento. Separe os atributos entre si com um só espaço.
 * As células e títulos ( ou ,   ou  , e  ) têm conteúdo. Por isso, separe os atributos do conteúdo usando uma só barra vertical . O conteúdo da célula pode ser colocado na mesma linha ou nas linhas seguintes.
 * Os elementos da tabela e das linhas ( e  ) não têm conteúdo. Não coloque a barra vertical  após os atributos opcionais. Se colocar, por erro, uma barra vertical depois dos atributos de um elemento de tabela ou de linha, o analisador sintático apaga a barra vertical e o último atributo se este estiver encostado na barra vertical!
 * Conteúdo pode (a) seguir seu elemento de célula na mesma linha após quaisquer atributos HTML opcionais ou (b) em linhas abaixo do elemento de célula. Conteúdo que usa wiki markup que precisa começar em uma nova linha, como listas, cabeçalhos, ou tabelas aninhadas, deve estar em sua própria nova linha.
 * Barra vertical como conteúdo. Para inserir um caractere de barra vertical em uma tabela, use o elemento wiki &lt;nowiki&gt; &lt;/nowiki&gt;.

Informações básicas
A tabela a seguir não possui bordas e um bom espaçamento mas mostra a estrutura mais simples com o elemento tabela.

{| style="width:100%" ! style="width: 50%;"|Você digita ! style="width: 50%;"|O resultado é
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

As células na mesma linha podem ser listadas em uma linha separadas por  (duas barras verticais). Se o texto na célula precisar conter uma quebra de linha, use  no lugar.

{| style="width:100%" ! style="width: 50%;"|Você digita ! style="width: 50%;"|O resultado é
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Extra spaces within cells in the wiki markup, as in the wiki markup below, do not affect the actual table rendering.

{| style="width:100%" ! style="width: 50%;"|Você digita ! style="width: 50%;"|O resultado é
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

You can have longer text or more complex wiki syntax inside table cells, too:

{| style="width:100%" ! style="width: 50%;"|Você digita ! style="width: 50%;"|O resultado é
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Table headers
Table headers can be created by using " " (exclamation mark) instead of " " (pipe symbol). Headers usually show up bold and centered by default.

{| style="width:100%" ! style="width: 50%;"|Você digita ! style="width: 50%;"|O resultado é
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Note: When using attributes as in the heading 'Item' a vertical bar '|' is used for separation. Not an exclamation character '!'.

Caption
A table caption can be added to the top of any table as follows.

class="wikitable"
Basic styling (light gray background, borders, padding and align left) can be achieved by adding class="wikitable".

HTML colspan and rowspan
You can use HTML colspan and rowspan attributes on cells for advanced layout.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

HTML attributes
You can add HTML attributes to tables. For the authoritative source on these, see the W3C's HTML Specification page on tables.

Attributes on tables
Placing attributes after the table start tag applies attributes to the entire table.

{| style="width:100%" ! style="width: 50%;"| You type ! style="width: 50%;"| You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Attributes on cells
You can put attributes on individual cells. For example, numbers may look better aligned right.

You can also use cell attributes when you are listing multiple cells on a single line. Note that the cells are separated by, and within each cell the attribute(s) and value are separated by.

{| style="width:100%" ! style="width: 50%;"| You type ! style="width: 50%;"| You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Attributes on rows
You can put attributes on individual rows, too.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Simple one-pixel table border
An example of a one-pixel table border:

{| style="width:100%" ! style="width:50%" | You type ! style="width:50%" | You get
 * style="padding: 5px;" |
 * style="padding: 5px;" |
 * style="padding: 20px;"|


 * }

Border width
If "border-width:" has only one number, it is for all four border sides: {| style="width:100%" ! style="width:50%" | You type ! style="width:50%" | You get
 * style="padding: 5px;" |
 * style="padding: 5px;" |
 * style="padding: 20px;"|


 * }

If "border-width:" has more than one number, the four numbers are for top, right, bottom, left (REMEMBER this order):

{| style="width:100%" ! style="width:50%" | You type ! style="width:50%" | You get
 * style="padding: 5px;" |
 * style="padding: 5px;" |
 * style="padding: 20px;"|


 * }


 * When there are fewer than 4 values, the value for left takes its default from the value for right, the value for bottom takes its default from the value for top, and the value for right takes its default from the value for top.

Another method to define the widths of the four sides of a cell is to use "border-left", "border-right", "border-top" and "border-bottom": {| style="width:100%" ! style="width:50%" | You type ! style="width:50%" | You get
 * style="padding: 5px;" |
 * style="padding: 5px;" |
 * style="padding: 20px;"|


 * }

With HTML attributes and CSS styles
CSS style attributes can be added with or without other HTML attributes.

Attributes
Attributes can be added to the caption and headers as follows.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Column width
Column width can be added as follows.

Accessibility of table header cells
Table header cells do not explicitly specify which table data cells they apply to (those on their right on the same row, or those below them on the same column). When the table is rendered in a visual 2D environment, this is usually easy to infer.

However when tables are rendered on non-visual media, you can help the browser to determine which table header cell applies to the description of any selected cell (in order to repeat its content in some accessibility helper) using a scope="row" or scope="col" attribute on table header cells. In most cases with simple tables, you'll use scope="col" on all header cells of the first row, and scope="row" on the first cell of the following rows:

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Table alignment
Table alignment is achieved by using CSS. The table alignment is controlled by margins. A fixed margin on one side will make the table to be aligned to that side, if on the opposite side the margin is defined as auto. To have a table center aligned, you should set both margins to auto

For example, a right-aligned table:

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

And a center-aligned table:

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Table floating around text
If you align a table to the right or the left side of the page, the text that comes after the table starts at the end of it, leaving an empty space around the table. You can make the text to be wrapped around the table by making the table to float around the text instead of just aligning it. This can be achieved using the  CSS attribute, which can specify where the table floats to the right side or to the left. When using float, margins doesn't control table alignment and can be used to specify the margin between the table and the surrounding text.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|

Cell contents alignment
The alignment of cell contents can be controlled with 2 different CSS properties:  and. can be specified at the table, row or individual cells, while  only can be specified at individual rows or cells.

{| style="width:100%" ! style="width: 50%;"|You type ! style="width: 50%;"|You get
 * style="padding: 5px;"|
 * style="padding: 5px;"|
 * style="padding: 5px;"|


 * }

Negative numbers
If you start a cell on a new line with a negative number with a minus sign (or a parameter that evaluates to a negative number), your table can get broken, because the characters  will be parsed as the wiki markup for table row, not table cell. To avoid this, insert a space before the value or use in-line cell markup.

CSS vs attributes
Table borders specified through CSS rather than the border attribute will render incorrectly in a small subset of text browsers.

Common attributes for columns, column groups and row groups
The MediaWiki syntax for tables currently offers no support for specifying common attributes for columns (with the HTML element ), column groups (HTML element  ) and row groups (HTML elements ,   and  ). Those standard HTML elements are not accepted even in their HTML or XHTML syntax.

All the rows and cells (header or data) of the table are rendered within a single implicit row group (HTML element ) without any attributes or styles.
