【问题描述】:
我正在使用一个小部件(我在网络上得到它)来调整表格列的大小。如果表头 <thead> 具有相同列数的行,但如果 colspan 属性设置为一行的单元格,则它工作正常。
假设表格中有两行,六列。第一个单元格将有colspan=6,第二个单元格将有所有列。在这种情况下,调整大小应该适用于第二行。但它不起作用。
谁能告诉我原因?
这是我的代码:

-
请制作一个 jsfiddle 来展示您的问题的工作演示,使用如下分隔代码:jsfiddle.net/RLURC(不工作)
-
@Valky我试图把它交给 jsfiddle。但它在那里不起作用。我在我的桌面上检查了它,它工作正常。
-
能否提供插件的js文件的链接?然后我们可以在小提琴中测试它。
-
@Valky 插件/小部件中没有更多代码。它大约25行。我通过Kept评论插件包含在上面的代码中。你可以复制整个代码,保存记事本并在您的桌面上运行。它应该可以工作...
-
抱歉,在不分离 CSS、JS 和 HTML 的情况下让它工作是一个非常糟糕的主意。试着让它在小提琴中工作,然后,如果真的有问题,我们可以帮助你解决它。或者也许将插件更改为 datatables.net 或 quocity.com/colresizable 插件,就像一个魅力(没有 UI)。
