Try a JavaScript tooltip library for a better result, something like OverLib.

One way to achieve similar effect would be through CSS:
实现类似效果的一种方法是通过 CSS：
<td>Cell content.
<div class="popup">
This is the popup.
<br>
Another line of popup.
</div>
</td>
And then use the following in CSS:
然后在 CSS 中使用以下内容：
td div.popup { display: none; }
td:hover div.popup { display: block; position: absolute; }
You will want to add some borders and background to make the popup look decent, but this should sketch the idea. It has some drawbacks though, for example the popup is not positioned relative to mouse but relative to the containing cell.
您将需要添加一些边框和背景以使弹出窗口看起来不错，但这应该可以勾勒出想法。但是它有一些缺点，例如弹出窗口不是相对于鼠标定位，而是相对于包含单元格。

可扩展标记语言 (XML) 1.1 W3C 建议说
? All line breaks MUST have been normalized on input to #xA as described in 2.11 End-of-Line Handling, so the rest of this algorithm operates on text normalized in this way. ?
? 如 2.11 行尾处理中所述，所有换行符都必须在#xA 的输入上进行规范化，因此该算法的其余部分对以这种方式规范化的文本进行操作。?

didn't work in my fb app.
However this did, beautifully (in Chrome FF and IE):

This should be OK, but is Internet Explorer specific:
这应该没问题，但特定于 Internet Explorer：
<td title="lineone
linetwo

As others have mentioned, the only other way is to use an HTML + JavaScript based tooltip if you're only interested in the tooltip. If this is for accessibility then you will probably need to stick to just single lines for consistency.
正如其他人所提到的，如果您只对工具提示感兴趣，那么唯一的其他方法是使用基于 HTML + JavaScript 的工具提示。如果这是为了可访问性，那么您可能需要坚持使用单行以保持一致性。

If you're looking to put line breaks into the tooltip that appears on mouseover, there's no reliable crossbrowser way to do that. You'd have to fall back to one of the many Javascript tooltip code samples
如果您想在鼠标悬停时出现的工具提示中添加换行符，则没有可靠的跨浏览器方法可以做到这一点。您必须退回到众多 Javascript 工具提示代码示例之一
