Examples
In the following example, an array of automation element objects representing the primary row or column header items of a table is retrieved.
For the purposes of this example, a relationship between the RowOrColumnMajor property and the row and column header items is demonstrated. However, a table can have row and column headers regardless of the RowOrColumnMajor property of the table.
