Topic on Project:Support desk

I am wondering if someone would be willing to work with me for a few minutes on formatting a table that includes and image gallery in 1 Column, a Large Image in a 2nd column and then a paragraph in a bottom row that I would like to have centered. I also have some issues with the layout on lower resolution screens. Here is page I have been editing. https://www.gatesofsurvival.com/wiki/index.php/Main_Page

All the editing Im trying to is in the Skills Section.I have been using the Tables wiki and its helped alot but I not very good at basic html and would appreciate it if anyone could spend a little time helping me.

Thanks

{| class="wikitable" 
|Some Image Gallery 
|A Large Image 
|- 
|colspan="2" style="text-align:center;"|a centered paragraph 
|}
