How do I vertically align a div inside a table cel

问题:

How do I vertically center a div that is inside a table cell?

HTML:

<tr class="rowClass">
    <td class="cellClass">
        <div class="divClass">Stuff</div>
    </td>
</tr>

CSS:

.rowClass {
    vertical-align:middle !important;
    height:90px;
}

.cellClass {
    vertical-align:middle !important;
    height:90px;
}

.divClass {
    vertical-align:middle !important;
    height:90px;
}

I know the class definitions are redundant, but I've been trying lots of different things. Why isn't the solution (whatever it is) intuitive. None of the "obvious" solutions that I tried would work.

回答1:

There is no need to defineheight in .divClass . write like this:

.cellClass {
    vertical-align:middle;
    height:90px;
    border:1px solid red;
}

With out any css itself you can do this with valign="middle" try this code.

<table width="100%" border="1" cellspacing="0" cellpadding="0">
  <tr>
    <th height="550" align="center" valign="middle" scope="col">

    <div>Hello</div>
    </th>
  </tr>
</table>

<table border=1>
<tr class="rowClass">
<td class="cellClass">
