Expanding on vc's answer, this will remove all rows that which each of it's columns contain either nothing or white space:

dataTable = dataTable.Rows.Cast().Where(row => !row.ItemArray.All(field => field is System.DBNull || string.Compare((field as string).Trim(), string.Empty) == 0)).CopyToDataTable();
