Table headers make content readable and much more accessible to screen reader users as they provide navigation information to assistive technologies.
As screen reader users navigate through the table, their screen reader reads each table cell and the header associated with it. This helps them to avoid losing context to helpful information at any point.
Use table headers
Position the cursor anywhere in a table.
Select the Table Design tab.
In the Table Style Options group, select the Header Row check box.
In the first row of the table, type the column headings.
