    //Create second table
    ITable table2 = worksheet.Tables.Add(worksheet.Range["A1:C6"], true);
    
    //Insert a table column before first column in first table
    table1.Columns.Add(0);
    
    //Insert a table column before first column in second table
    table2.Columns.Add(0);
    
    //Delete the first table column from the first table.
