Examples
In the following example, an array of AutomationElement objects representing the primary row or column headers 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.

Remarks
This identifier is used by UI Automation client applications. UI Automation providers should use the equivalent field in TablePatternIdentifiers.
The order of the headers returned will be consistent within a provider, but not necessarily across providers.
This property is not present in TablePattern.TablePatternInformation and must be retrieved by using GetCurrentPropertyValue or GetCachedPropertyValue.
