兩列頁中表中的 Vspace

我製作了一個跨越兩列頁面頂部的表格，但最後一列有一個問題，其中 $j$ 非常接近上面的 hline，而同一行中的其他元素具有相同的垂直高度。最後一列中的「transition」標題也會出現同樣的問題。有沒有辦法讓第一行更寬一些（有 $\lambda$ 和轉換的行）？如何解決這些問題？

答案1

我不會使用m該表的列類型。取而代之的是，我將使用X列提供的居中形式（由包提供tabularx），部分是為了讓 LaTeX 處理確定列寬度的瑣事。另外，我會使用套件的畫線巨集booktabs來獲得間隔良好的水平線；另外，我會省略所有垂直線。

該表唯一「棘手」的方面是，雖然大多數單元格的內容應居中，但第一列的前 5 個資料行的內容將受益於在小數分隔符號上對齊。這可以透過（i）使用第一列的S列類型（由套件提供siunitx）和（ii）將那些應在花括號對中居中的項目包含在第一列中來實現。

最後，我相信將巨集設為\extrarowheight該值更容易，而不是手動為每行添加 1 毫米的額外行高。

附錄OP 告訴我他/她正在使用revtex4文檔類，該類似乎與booktabs套件及其規則繪製巨集不相容。 :-(

這是一個替代解決方案，它適用於revtex4文件類別以及許多其他文件類別。它使用tabular*環境而不是環境tabularx，並在選定的位置插入（印刷）支柱，以獲得由 和 繪製的線條與線條上方和下方的材料之間更好的垂直\hline分隔\cline。

順便說一句，我仍然不會在這個解決方案中使用任何垂直線。
