在多行（表格）中添加方程

在多行（表格）中添加方程

我想在多行单元格中添加一个方程，使用表格和定义的宽度。它在表格中的任何地方都有效，除了一个由另外两个多行组成的多行单元格。在这种情况下，我收到错误。（单元格在附图中显示为此处）。您知道如何解决它吗？谢谢！在此处输入图片描述

我没有DissOnlineLatex文档类，因此在下面我使用了文章。

我不会将equation环境放在tabular环境中，我原以为这会导致一堆错误。所以，我很惊讶你在单元格内只得到一个错误\multirow。我猜这是因为你使用的是M-column 类型。如果你想把equation环境放在单元格内，\multirow那么显而易见的做法就是把它放在环境equation内minipage。使用这个似乎可以做你想做的事：

从理论上讲，将环境宽度设置minipage为\linbewidth应该会给出正确的宽度。我通过反复试验发现使用0.97\linewidth效果更好，因为这会使此单元格中的方程编号与其他方程编号正确对齐。这是您修改后的 MWE：
