What you want to do can't be done via the Insert Table dialogue box. You would need a separate macro to populate the table after you've created it. Alternatively, you could use a macro to both create and populate the table. The following macro takes the latter approach
Code:
Sub AddTable()
Application.ScreenUpdating = False
Dim StrNum As String, NumRows As Long, oTbl As Table, r As Long
StrNum = InputBox("How Many Pairs of Rows?")
If IsNumeric(StrNum) = False Then Exit Sub
NumRows = CLng(StrNum) * 2
Set oTbl = Selection.Tables.Add(Range:=Selection.Range, NumRows:=NumRows, NumColumns:=2)
With oTbl
.Borders.Enable = True
With .Range.ParagraphFormat
.SpaceBefore = 0
.SpaceAfter = 0
End With
If NumRows = 2 Then
.Cell(1, 1).Range.Text = "<2FG>"
.Cell(1, 2).Range.Text = "<2FG>"
.Cell(2, 1).Range.Text = "<LLA>(a)"
.Cell(2, 2).Range.Text = "<LLA>(b)"
Else
For r = 1 To NumRows Step 2
.Cell(r, 1).Range.Text = "<4FG>"
.Cell(r, 2).Range.Text = "<4FG>"
.Cell(r + 1, 1).Range.Text = "<LLA>(" & Chr(96 + r) & ")"
.Cell(r + 1, 2).Range.Text = "<LLA>(" & Chr(97 + r) & ")"
Next
End If
End With
Application.ScreenUpdating = True
End Sub
