Check for empty Cell

Columns = Enum

 DataTable dt = new DataTable();

  DataRow dr = dt.NewRow();

if (!dr.IsNull("ColumnName"))
{
    dt.Rows.Add(dr);
    dr = dt.NewRow();
    CurentColumn = Columns.none;
    if (Headline)
    {
        HeadlineRow.Add(rowNum);
        Headline = false;
    }   
    rowNum++;
}
