How to fix height of TR?

Question

Is it possible to fix the height of a row (tr) on a table?

The problem appears when I shrink the window of the browser, some rows start playing around, and I can not fix the height of the row.

I tried several ways: tr width="20" / tr style="height:20px" / td height="20" / td style="height:20px"

I am using IE7

Style

.tableContainer{
    color:#0076BF;
    margin: -10px 0px -10px 0px;
    border-spacing: 10px;
    empty-cells:show;
    width:90%;
    text-align:left;
} 

.tableContainer tr td{
    white-space:nowrap;
    text-align:left;
}

HTML code.

<table class="tableContainer" cellspacing="10px">
    <tr style="height:15px;">
        <td>NHS Number</td>
        <td>&#160;</td>
        <td>Date of Visit</td>
        <td>&#160;</td>
        <td colspan="3">Care Time Started</td>
        <td>&#160;</td>
        <td rowspan="2" style="text-align:right;vertical-align:bottom;">&#9745;</td>
        <td rowspan="2" style="font-weight:bold;vertical-align:bottom;">Tick when<br/>                        care starts</td>
    </tr>
    <tr>
        <td width="90" class="tableContainerRow2">&#160;</td>
        <td >&#160;</td>
        <td width="80" class="tableContainerRow2">&#160;</td>
        <td >&#160;</td>
        <td width="40" class="tableContainerRow2">&#160;</td>
        <td  width="5">:</td>
        <td width="40" class="tableContainerRow2">&#160;</td>        
        <td >&#160;</td>
    </tr>
</table>

Tables are iffy (at least, in IE) when it comes to fixing heights and not wrapping text. I think you'll find that the only solution is to put the text inside a div element, like so:

td.container > div {
    width: 100%;
    height: 100%;
    overflow:hidden;
}
td.container {
    height: 20px;
}

<table>
    <tr>
        <td class="container">
            <div>This is a long line of text designed not to wrap 
                 when the container becomes too small.</div>
        </td>
    </tr>
</table>

This way, the div's height is that of the containing cell and the text cannot grow the div, keeping the cell/row the same height no matter what the window size is.
