OK, here are 4 Functions for determining the first and Last rows and columns on a sheet:
these should be more robust than the rather volatile UsedRange method.

Private Function FirstRow(TheWorksheet As Worksheet) As Long
If WorksheetFunction.CountA(TheWorksheet.Cells) > 0 Then
    FirstRow = Cells.Find(What:="*", After:=[A1], SearchOrder:=xlByRows, SearchDirection:=xlNext).Row
End If
End Function
Private Function FirstColumn(TheWorksheet As Worksheet) As Long
If WorksheetFunction.CountA(TheWorksheet.Cells) > 0 Then
    FirstColumn = Cells.Find(What:="*", After:=[A1], SearchOrder:=xlByColumns, SearchDirection:=xlNext).Column
End If
End Function
Private Function LastRow(TheWorksheet As Worksheet) As Long
If WorksheetFunction.CountA(TheWorksheet.Cells) > 0 Then
    LastRow = Cells.Find(What:="*", After:=[A1], SearchOrder:=xlByRows, SearchDirection:=xlPrevious).Row
End If
End Function
Private Function LastColumn(TheWorksheet As Worksheet) As Long
If WorksheetFunction.CountA(TheWorksheet.Cells) > 0 Then
    LastColumn = Cells.Find(What:="*", After:=[A1], SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column
End If
End Function

Sub test()

Dim ws As Worksheet
Dim TopLeftC As Range
Dim TopRightC As Range
Set ws = ActiveSheet

lRow = LastRow(ws)
lCol = LastColumn(ws)

fRow = FirstRow(ws)
fCol = FirstColumn(ws)

Set TopLeftC = ws.Cells(fRow, fCol)
Set TopRightC = ws.Cells(fRow, lCol)

TopLeft = Replace(TopLeftC.Address, "$", "")
TopRight = Replace(TopRightC.Address, "$", "")

MsgBox ("Left Header Cell : '" & TopLeft & "'" & vbCrLf & "Right Header Cell: '" & TopRight & "'")


End Sub

Hello All,

For your excellent feedbacks: I want get all other different approaches towards this issue.

The_Barman: Thank your solution works for me. you used used range. I would now want to see if there is way other approach (s) different from this method.

 
imnorie: How can you tell which row is the row with headings?

The top most row is most likely to be the row with headings - now the top-most row could be on row3 or row 5 or any row

 What are the extreme left and extreme right headings called? You said the row would vary but would the columns always be the same?
C1, C9
Actually, the users would be adding in more columns at the end of the table, so the last column will change with time.


 if you can come up with different approaches to resolve this issue.

You still haven't explained how the correct row can be found.

Is there a particular value to look for?

Perhaps a format?

Or perhaps we need to find a value first then move up/down a certain no of rows?

Another approach. This is with the assumption that there is no other instance of "C1" in the sheet.

Sub TopColumns2()
    
    Dim wb As Workbook
    Dim ws As Worksheet
    Dim lVal As String
    Dim lRange As Range
    
    Set wb = ThisWorkbook
    Set ws = wb.Worksheets("Sheet1")
    
    lVal = "C1"
    
    On Error GoTo ErrHandler
    Set lRange = ws.UsedRange.Find(What:=lVal, LookAt:=xlWhole)
    MsgBox "Left header cell: " & """" & WorksheetFunction.Substitute(lRange.Address, "$", "") & """" _
            & vbCrLf & "Right header cell: " & """" & WorksheetFunction.Substitute(lRange.End(xlToRight).Address, "$", "") & """"
    Exit Sub
    
ErrHandler:
MsgBox (lVal & " not found.")

End Sub

Perfection to the ultimate.
 Awesome, this is great. I love all your feedbacks. Now I have got a robust collection of function I use reliably. Thank you all for the help :)
