如何使用 pgfplotstable 修改長表的版面

Question

為了準備一系列包含複雜長表的工業報告，我結合了我在網站上找到的程式碼範例，這看起來很有希望。在我的領域，儘管通常建議做法，但單元格需要用垂直線和水平線分隔。在MWE（非常簡化與實際需要）中，我仍然面臨兩個問題：資料行1和2之間沒有水平線。我也歡迎任何改進程式碼的提示（我不清楚在哪裡最好地進行列的格式設置，例如在每行之間定義一條水平線）和/或視覺外觀。 MWE 中的垂直線不是連續的。

Answer 1

讓我們從問題的簡單方面開始：

• 如果喜歡使用垂直線，則不要使用 中的規則\booktabs。相反，他們使用\hline

• 對於垂直線，我建議執行以下操作：

  every odd column/.style ={% column type/.add={|}{} }, every even column/.style ={% column type/.add={|}{} }, every last column/.style ={% column type/.add={}{|} },

• 合我口味比較好說every nth row={1}{before row=\hline}。表格下的文字（下一頁繼續）沒有在其下劃線。
