ListColumn Object (Excel)
Represents a column in a table.
Remarks
The ListColumn object is a member of the ListColumns collection. The ListColumns collection contains all the columns in a table (ListObject object).
Use the ListColumns property of the ListObject object to return a ListColumns collection.
Example
The following example adds a new ListColumn object to the default ListObject object in the first worksheet of the active workbook. Because no position is specified, a new rightmost column is added.
Sub AddListColumn()
Dim wrksht As Worksheet
Dim objListCol As ListColumn
Set wrksht = ActiveWorkbook.Worksheets("Sheet1")
Set objListCol = wrksht.ListObjects(1).ListColumns.Add
End Sub
