What to do
Use a simple table structure, and use column headers.
How to find it
To make sure that tables don't contain split cells, merged cells, or nested tables, use the Accessibility Checker.
You can also visually scan your tables to check that they don't have any completely blank rows or columns.
Why do it
Badly created tables can cause difficulties for screen readers or for those tabbing through information on a document.
If a table is nested within another table or if a cell is merged or split, the screen reader can’t provide helpful information.
Blank cells in a table could also mislead a screen reader into thinking that there is nothing more in the table.
Screen readers also use header information to identify rows and columns.
