Tables
Tables must be constructed and formatted correctly so that users can understand the context between the column and row data. This is especially important for people who use screen readers. Note that many screen readers may still have difficulty reading tables, however the formatting is still useful for when converting a Microsoft Word Document to a PDF.
To create a table, go to the Insert tab and select Table. Then select Insert Table...
Select the number column and rows.
It's good practice to use the first column row for table headers. This can help readers understand the context of the data in the following rows. Verify that the Header Row box and First Column box are checkmarked in the Table Style Options of the Design tab. Note: for Windows 11, the tab is labeled Table Design.
If the table is more than one page, you can also specify to repeat the table headers so they display at the top of the table for each page. Right-click on the table headers and select Table Properties...
Go to the Row tab and select Repeat as header row at the top of each page.
Headers will now display on each page.
