This example creates a table and then sets a fixed row height of 0.5 inch (36 points) for the first row.
Set newDoc = Documents.Add
Set aTable = _
newDoc.Tables.Add(Range:=Selection.Range, NumRows:=3, _
NumColumns:=3)
aTable.Rows(1).SetHeight RowHeight:=InchesToPoints(0.5), _
HeightRule:=wdRowHeightExactly
This example sets the row height of the selected cells to at least 18 points.
If Selection.Information(wdWithInTable) = True Then
Selection.Cells.SetHeight RowHeight:=18, _
HeightRule:=wdRowHeightAtLeast
Else
MsgBox "The insertion point is not in a table."
End If
