I have some tables that insist the columns should be the same width, how do I specify them?

to be clear, I want the left most column to narrow so that the other headers will fit on one line

Code sample 

```
<div>
    <table style="width:610px;border-style:inset; border:1px; border-color:#000000; padding:3px;">
    <tr class="propGridHeader">
        <td style="width:150px!important;border:1px;border-style:inset;border-color:#000000;text-align:left;">Records: <asp:Label ID="lblHourCount" runat="server" /></td>
        <td style="width:153.3px;border:1px;border-style:inset;border-color:#000000;text-align:center;">Fixed Price</td>
        <td style="width:153.3px;border:1px;border-style:inset;border-color:#000000;text-align:center;">Liquidated Heat Rate</td>
        <td style="width:153.3px;border:1px;border-style:inset;border-color:#000000;text-align:center;">Liquidated Spark Spread</td>
    </tr>
    <tr>
        <td style="width:150px!important;border:1px;border-style:inset;border-color:#000000;" class="propDarkGrid">Average</td>
        <td style="width:153.3px;border:1px;border-style:inset;border-color:#000000;text-align:right;" class="propLightGrid"><asp:Label id="lblHourAvgFP" runat="server" /></td>
        <td style="width:153.3px;border:1px;border-style:inset;border-color:#000000;text-align:right;" class="propLightGrid"><asp:Label id="lblHourAvgHR" runat="server" /></td>
        <td style="width:153.3px;border:1px;border-style:inset;border-color:#000000;text-align:right;" class="propLightGrid"><asp:Label id="lblHourAvgSS" runat="server"  /></td>
    </tr>

```
