Per section 11.2.1 of the NVDA user guide:

After moving to the first cell in the column or row containing the headers, use one of the following commands:

Name	Key	Description
Set column headers	NVDA+shift+c	Pressing this once tells NVDA this is the first header cell in the row that contains column headers, which should be automatically announced when moving between columns below this row. Pressing twice will clear the setting.
Set row headers	NVDA+shift+r	Pressing this once tells NVDA this is the first header cell in the column that contains row headers, which should be automatically announced when moving between rows after this column. Pressing twice will clear the setting.

These settings will be stored in the workbook as defined name ranges compatible with other screen readers such as JAWS. This means that users of other screen readers who open this workbook at a later date will automatically have the row and column headers already set.
