Resize Listobject Table dynamically with VBA

The problem is Range("A1" & Lrow1) returns a Range of $A$112, because you are passing the Range function the result of the catenation of "A1" & "12".

Try replacing this line:

ob.Resize Range("A1" & Lrow1)

With this one:

ob.Resize ob.Range.Resize(Lrow1)

If you need to resize only the row-dimension:

Dim tbl As ListObject

Set tbl = ActiveSheet.ListObjects("YourTableName")
With tbl.Range
    tbl.Resize .Resize(.CurrentRegion.Rows.Count) 'NOTE: unlike the Range.Resize proprty, the Table.Resize
                                                  'method's argument is a Range object (not a size spec).
End With

Resizing only the column-dimension would be symmetrical:

With tbl.Range
    tbl.Resize .Resize(, .CurrentRegion.Columns.Count)
End With

There's way avoiding calculating last row:

Sub ResizeListDyn()
    Dim tbl As ListObject
    Set tbl = ActiveSheet.ListObjects(1)
    tbl.Resize tbl.Range.CurrentRegion
End Sub
