在HTML正文中尝试:

<table>
    <tr>
        <td>
            <div style="word-wrap: break-word; width: 800px">
                Hello world, how are you? More text here to see if it wraps after a long while of writing and it does on Firefox but I have not tested it on Chrome yet. It also works wonders if you have a medium to long paragraph. Just avoid writing in the CSS file that the words have to break-all, that's a small tip.
            </div>
        </td>
    </tr>
</table>

在CSS正文尝试:

background-size: auto;

table-layout: fixed;
