There are three HTML attributes you need to handle: colspan, rowspan, and align.

有三种 HTML 属性需要处理： colspan 、 rowspan 和 align 。

The colspan and rowspan attributes map directly to the XSL-FO number-columns-spanned and number-rows-spanned attributes, so they aren't difficult to handle.

colspan和rowspan属性直接映射成xsl - FO number - columns - spanned和number - rows - spanned属性，因此处理它们并不困难。
