我正在使用 Nikos Alexandris 提出的方法“如何在 LyX 的长表中应用隔行着色？”
在有限的范围内有效，但阴影行不会填满整个页面宽度。每个单元格都有阴影，但阴影会破坏列线，并且阴影中有间隙。
这是我的示例 tex 代码，用于执行破碎的阴影处理。tex 是自动生成的，因此我仅显示一个简短的表格。实际数据更长，并且通常应该跨越具有重复标题的页面。

colortbl不太喜欢\extracolsep。对于单个单元格，你可以摆弄可选的悬垂参数，但对于行来说，这有点困难。
而且，您的桌子不是全宽，因为胶水是通过桌子两侧的胶水来\extracolsep平衡的。\LTleft\LTright
如果你把它做成全宽，制作彩色带就容易多了，因为你事先知道它们需要多大：
