从html生成excel
我想生成Excel文件，我的数据是以HTMLstring的forms。 我有一个很less的列和行的HTML表格。 我在java中生成了一个具有n行和n列的巨大HTML表，并将该string保存到一个平面文件中，并将该文件命名为mydata.html或mydata.xls。 当使用Microsoft Excel打开这个文件时，它以列式格式显示表格。 该文件呈现完美。 这是在Excel中生成文件最简单的方法。
请附上示例HTML文件。 将此文件保存为mydata.html或mydata.xls，然后使用Microsoft Excel打开它。 如果保存为.xls，请在打开时在Excel对话框中单击“是”。

标记）导致相邻单元跳转到下一行。 请使用excel打开附加的HTML文件。 第2栏和第3栏有3个段落。 请注意第3栏第2段的alignment。第3栏第2段不是从第1段开始，而是从第2栏的第2段开始。第2段的上方有许多空格第3列。我希望段落2应该在段落1之后开始。如果html文件在浏览器中打开，段落的alignment是完美的。
我想第2段应该在第1段之后开始。请find附加的图像文件。 
您可以使用换行符标记<br>而不是段落标记<p> ，只需添加样式…. style="mso-data-placement:same-cell;" ..这是你的例子
