Accessible Table Builder
Use the + and - controls to add or removes rows and columns for your table. Alternatively, you can enter a number directly into the text inputs to generate the necessary table structre.
You can choose to have table headers along the top or left of the table, or both; it is not possible to create multiple rows or columns of headers (as you might find on longer tables).
The tool will generate scope or id/headers attributes automatically, depending on whether your table has just top/left header cells or headers along both axes, respectively.
