Shrink a cell (in an absolutely-positioned ASP.NET table) to fit its contents?

Answer 1

Why not add a width to the Content2 cell? Something like:

<asp:Table runat="server" style="position: absolute;
    left: 0%; top: 82%; right: 0%; bottom: 0%; width: 100%; height: 18%"
    CellPadding="0" CellSpacing="0" GridLines="Both">
    <asp:TableRow>
        <asp:TableCell>
            Content1
        </asp:TableCell>

        <asp:TableCell Width="2.5%">
        </asp:TableCell>

        <asp:TableCell Width="97.5%">
            Content2
        </asp:TableCell>
    </asp:TableRow>
</asp:Table>
