3.解释，所要实现的是在对应的TD项，鼠标移到上面，则显示相应的title提示。但是每个feature_element都要按code+空格+冒号+空格+description+逗号的形式显示，并尽可能在屏幕上显示满一行后，再换行。从上面的脚本可以看出，它还有字符限制，显示满指定的字符数后，即加一句话There are more features which cannot be displayed here.";这个脚本是我自己实现的。目的基本到，但是：
HTML TD的title属性里的内容，如果包含任一空格，就可能会自动换行，不能在屏幕显示一行后再显示。而要求显示的内容里的空格却不能去掉，另外feature_element的description属性值也可能有空格。目前我找了太多资料也没有方法控制TD的title显示方式，把字符里的空格在脚本里转换成nbsp或 等代码形式，则它会把代码在提示中原样显示，这也不是我们需要的。
哪位高手有什么别的解决方案呀？急死了。另外最好不要用复杂的脚本重新实现TD的 title.
