A layout table is a table used to provide some sort of visual structure to a page, sometimes people want to design columns on a page, set up a schedule, etc. When you use a table for anything but providing data, you are using a table for layout. Layout tables are inadvisable.
For more guidance on when to use a table, read this article on making tables accessible.
Configuring Tables for Accessibility
You will need to designate the table headers in order to make the data table accessible. Adding a caption or table title is helpful. A complex table will need a summary.
If you did not initially set up the headers when you created the table, right-click on the table to open up the Table Properties again.
- Do not use tables to layout content
- Designate row and column headings in the table properties
- Provide a table title or caption
- Provide summaries for complex tables
- For data tables that have two or more logical levels of row or column headers, separate the data into two simpler tables instead of one complex table.
