Answer 1

The problem is exactly about your DataType of the column. If you have a row with dynamically added columns without DataType like that (it may be a result of a manual calculation or cross-tab query-like)

myTable.Columns.Add("AddedColumn");

You will probably face with the column conversion issue. Instead, If you change your add method with pointing DataType like below

myTable.Columns.Add("AddedColumn", typeof(System.Int32));

It will work I think. It's what I experienced & fixed before...
