I am using dreamweaver to create a webpage. I want the table border to be black but I do not want the cells to have borders so I set them to white. It looks fine in internet explorer but the borders still show in a greyish color in mozilla and netscape. Can anyone help? Thanks

You should be able to specify a single border on the outside of a table using CSS. I would avoid trying to style something that doesn't need style. Try this:

<table style="border:1px solid black;">
    <tr>
        <td>cell 1</td>
        <td>cell 2</td>
        <td>cell 3</td>
    </tr>
</table>

You can also pull this style out into a linked style sheet.

#my_table {
     border:1px solid black;
}

<table id="my_table">
    <tr>
        <td>cell 1</td>
        <td>cell 2</td>
        <td>cell 3</td>
    </tr>
</table>
