我正在使用 Nikos Alexandris 提出的方法“如何在 LyX 的長表中應用交替行著色？”
工作範圍有限，但陰影行不會填滿頁面的整個寬度。每個單元格都有陰影，但陰影會破壞列線並且陰影中存在間隙。
這是我的範例 tex 程式碼，它執行損壞的著色。 tex 是自動產生的，所以我只顯示一個簡短的表格。真實資料較長，通常應跨越具有重複標題的頁面。

答案1
colortbl不太喜歡\extracolsep。對於單一單元格，您可以擺弄可選的懸垂參數，但對於行來說，這有點困難。
此外，您的桌子不是全寬，因為膠水是由桌子兩側的膠水平衡\extracolsep的。\LTleft\LTright
如果將其設為全寬，則製作色帶會容易得多，因為您事先知道它們需要有多大：
