<logic:present name="list">
  <logic:iterate id="supplierinfo" name="list">
  <tr>
            <td align="center"> <bean:write name="supplierinfo" property="phone"/> </td>
 
    <td align="center" > <bean:write name="supplierinfo" property="fax"/> </td>
  <td align="center" > <bean:write name="supplierinfo" property="email"/> </td>
          <td align="center" > <bean:write name="supplierinfo" property="suppstate"/> </td>//如何讓當suppstate等於2時這整行背景色變為紅色，謝謝，在線等

        </logic:iterate>
</logic:present>
