我知道这是与表相关的错误的一个非常常见的现象，所以提前感谢您的任何帮助（我已经很累了:-)）。
我有一张表，由于某种原因，它拒绝编译。我认为它以前就是这样的，我看不出错误的变化发生在哪里。

如您所见，错误不是缺少包或首字母缩略词（至少我认为是这样），尝试使用 sharelatex 或 overleaf 会返回错误：
./main.tex:42: Undefined control sequence.

这确实很难解决:-(。
谢谢您对此的任何启发！
答案1
正如评论中提到的，您收到错误是因为命令\checkmark未定义。通过加载定义\checkmark命令的包（例如），amssymb可以使您的代码可编译。
由于您的表格很宽，我建议不要使用，resizebox因为它会导致字体大小小且不一致，难以辨认。在以下 MWE 中，我更改了表格的总体布局，使其适合一页。

与您的原始代码相比，我做了以下更改：
- 删除列标题中的粗体。
- 从包中的规则中删除了所有垂直线并替换了水平线，
booktabs并在其周围添加了适当的空白。 - 旋转第一列的内容（代码
\rothead取自此处：https://tex.stackexchange.com/a/429133/134144） - 用于
threeparttable将“多租户”列中的长文本放入表格注释中。 - 减少了包含列的复选标记之间的距离，以节省一些水平空间。
- 添加了包含数字的新第二列。这样，相应文本的第二行及后续行将自动缩进。
- 对“问题”列使用固定宽度且右对齐的列，以便实现自动换行。
X从包中使用灵活宽度的列tabularx，以使表格与文本宽度一样宽。- 将复选标记水平居中放置在其对应的列中。
- 在列的上方和下方添加了一些额外的垂直空白以引导读者的视线。
- ...
答案2
这里有一个解决方案，它 (a) 以横向格式呈现表格，并且 (b) 允许在两列中自动换行，从而避免使用\resizebox。还请注意，我简化了第一列中的材料，主要是通过获取\multirow“包装器”。（哦，一定要确保amssymb包已加载，以访问\checkmark宏。）
