Long word wrap in nested tables

问题

I'm trying to wrap a long word. I have seen this post : How to prevent long words from breaking my div?

It works great in a simple case like this :

.wrapWords
{
    white-space: pre;           /* CSS 2.0 */
    white-space: pre-wrap;      /* CSS 2.1 */
    white-space: pre-line;      /* CSS 3.0 */
    white-space: -pre-wrap;     /* Opera 4-6 */
    white-space: -o-pre-wrap;   /* Opera 7 */
    white-space: -moz-pre-wrap; /* Mozilla */
    white-space: -hp-pre-wrap;  /* HP Printers */
    word-wrap: break-word;      /* IE 5+ */

}

<!-- This wraps correctly -->
<div style="width:145px;">
    <div class="wrapWords" style="width:100%;">
        <a href="#">AAAAAAAAAAAAAAAAAA</a>
    </div>
<div>

But my case has two nested tables like this :

<!-- This doesn't work -->
<table style="width:100%;">
    <tr>
        <td style="width:145px;">
            <table style="width:100%;">
                <tr>
                    <td style="width:100%;">
                        <div class="wrapWords" style="width:100%;">
                            <a href="#">BBBBBBBBBBBBBBBBBB</a>
                        </div>
                    </td>
                    <td>
                    </td>
                </tr>
            </table>
        </td>
        <td>
        </td>
    </tr>
</table>

回答1:

table is taking the table-layout: auto; by default so as per contents increase the width also increases so you need to set table-layout to fixed.

table{
    table-layout: fixed;
}

demo

回答2:

There are 2 completely different algorithms for table layout: with or without table-layout: fixed

Former will adapt width of cells to the author's will
Latter will adapt width of cells to the content (the relative quantity/width/whatever of content in cells)

I think this is what you are looking for.

WORKING DEMO

The HTML:

<!-- This wraps correctly -->
<div style="width:145px;">
    <div class="wrapWords" style="width:100%;">
        <a href="#">AAAAAAAAAAAAAAAAAA</a>
    </div>
<div>

<!-- This doesn't work -->
<table style="width:100%;">
    <tr>
        <td style="width:145px;">
            <table style="width:100%;">
                <tr>
                    <td style="width:130px;">
                        <div class="wrapWords" style="width:inherit; display:inline-block;">
                            <a href="#">BBBBBBBBBBBBBBBBBB</a>
                        </div>
                    </td>
                    <td>
                    </td>
                </tr>
            </table>
        </td>
        <td>
        </td>
    </tr>
</table>

The Logic:

The div and td have different display characteristics. You need to make your div which is nested inside the td to change its display to, for instance here inline-block with a fixed width to achive what you are looking for.

Hope this helps.
