Increase HTML Table cell Height based on TextArea (TextBox) Height in ASP.Net

Hi

How to auto height when one td tag height is increased or decreased based on movement another td should increase height or decrease.

Here I want when Textbox is increased by dragging then Post Name td height also increased as compare to textbox td 

<tr>
    <td style="border:solid 1px;border-collapse:collapse;width:40%;height:auto;">
              Post Name
    </td>
    <td style="border:solid 1px;border-collapse:collapse;width:60%;height:50px;">
        <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine" style="width:90%"></asp:TextBox>
    </td>
</tr>
