body: <p>I currently have :</p>
  
  <pre><code>&lt;asp:GridView ID="BalanceCheckDataGridView" runat="server"  AutoGenerateColumns="false"&gt;
    &lt;Columns&gt;
           &lt;asp:BoundField ItemStyle-Width="30%" DataField="Company" HeaderText="Company" /&gt;
           &lt;asp:BoundField ItemStyle-Width="30%" DataField="Balance" HeaderText="Balance" /&gt;
