Error: "index 1 does not have a value" how to fix it?

Error when click on datagridview contain data...(Row, Cells, Header)
 
I don't understand error!
 
I think problem is here in the below code...
 

private void CreateTable(DataGridView grdvTest, ref DataTable table)
        {
            if (dgvResults.CurrentRow.Cells[1].Value != null)
            {
                int num = 0;
                while (num < grdvTest.ColumnCount)
                {
                    table.Columns.Add(grdvTest.Columns[num].HeaderText);
                    num++;
                }
                foreach (DataGridViewRow row in (IEnumerable)grdvTest.Rows)
                {
                    DataRow row2 = table.NewRow();
                    for (num = 0; num < row.Cells.Count; num++)
                    {
                        //row2[num] = (row.Cells[num].Value != null) ? row.Cells[num].Value.ToString().Replace(" ", " ") : "";
                        if (row.Cells[num].Value != null)
                            row2[num] = row.Cells[num].Value.ToString().Replace(" ", " ");
                        else
                            row2[num] = "";
                    }
                    table.Rows.Add(row2);
                }
            }
