longtable、math coloumn、rowcolor 和 arraystretch 的一些問題

我有一個longtable交替的數學列rowcolor和兩個數學列。當行的內容位於單行中並在行內容的上方和下方進行填充時，行顏色將按預期工作。有些條目對兩列都有效，因此位於中間。但總的來說，這張桌子看起來相當難看:(

但是，如果內容跨越多行，或存在整數符號，則行顏色會觸及內容，且沒有填入。我嘗試過增加arraystretch（已經是 2 並且沒有任何區別），但它沒有幫助。我也按照一些答案中的建議嘗試過makecell軟體包，但效果不佳，也嘗試過extrarowheight。我嘗試的另一件事是在每行的換行符後面手動添加空格\\[5pt]，但這只能解決底部接觸下一個彩色行及其變數的問題。在某些情況下，我必須添加 8pt 或 10pt 以獲得更好的外觀。可以理解的是，內容的頂部不受行後添加空格的影響。

請建議可以做什麼。任何其他包而不是longtable任何其他一般使桌子更好的提示將不勝感激。如果給定列中的所有條目都可以對齊，那就更好了。

作為克拉拉漂亮答案的補充，稍微改變了表格版面：

longtable基於cellspace額外間距的解決方案。

LaTeX 預設情況下有一些更正。首先，我透過新增一條不可見的規則來拉伸第一行。其次，在最後一行之前，我將表達式括在\cramped和中，減少了分數中上標所佔用的空間\smash。
