True if the specified selection or range is collapsed and is located at the end-of-row mark in a table. Read-only Boolean.
Note This property is the equivalent of the following expression:
Selection.Information(wdAtEndOfRowMarker)
Example
This example collapses the selection and selects the current row if the insertion point is at the end of the row (just before the end-of-row mark).
Selection.Collapse Direction:=wdCollapseEnd
If Selection.IsEndOfRowMark = True Then
Selection.Rows(1).Select
End If
