在多行中加入方程式（表）

在多行中加入方程式（表）

我想使用表格和定義的寬度在多行單元格中添加一個方程式。它在表中的任何地方都有效，除了一個單元格是由另外兩個多行組成的多行。在這種情況下，我收到錯誤。 （該儲存格在附圖中顯示為此處）。您知道如何解決嗎？謝謝你！在此輸入影像描述

答案1

我沒有DissOnlineLatex文檔類，所以我在下面使用了文章。

我不會將equation環境放入tabular環境中，我認為這會導致一堆錯誤。所以，我很驚訝你在\multirow單元格內只得到一個錯誤。我想這有效是因為您使用的是M-column 類型。如果你想在細胞equation內部放置一個環境，\multirow​​那麼顯而易見的事情就是在細胞equation內部放置一個minipage環境。使用這個似乎可以做你想做的事：

理論上，將環境的寬度設定minipage為應該給出正確的寬度。\linbewidth透過反覆試驗，我發現使用0.97\linewidth效果更好，因為這使得該單元格中的方程式編號與其他方程式編號正確對齊。這是您修改後的 MWE：
