我刚刚升级了我的 texlive 发行版，现在无法再在加载\\[x pt]时使用语法在表格行中插入空格。colortbl
看来最近的更改可能array.sty是问题所在，因为这是最近唯一更改的包。
有人可以建议一个解决方法吗？

抱歉，修补有点棘手，所以我colortbl.sty在下面发布了一个新的，你可以测试一下吗

答案2
array.sty 中的核心问题是由于缺少一些代码\multicolumn，需要一些额外的代码。David 的回答中对 colortbl 的建议修复并不完整，还需要一些额外的代码。两者都在
https://github.com/latex3/latex2e/issues/42修复版本将在几天内发布。
