xltabular 与多列和 \kill 结合使用时会产生错误

xltabular 与多列和 \kill 结合使用时会产生错误

我需要做的是设置 20 列等宽，并使用多列。为了将表格扩展到 \textwidth，我需要使用 \kill。解释可以在这里找到Tabularx（xltabular）仅包含多列，无法正确展开

现在我收到此错误，! Missing } inserted. 这仅当 xltabular 与多列、X 类型的列和命令结合使用时才会发生\kill。这发生在环境中pdfTeX, Version 3.14159265-2.6-1.40.18 (TeX Live 2017)，在pdfTeX, Version 3.14159265-2.6-1.40.21 (MiKTeX 20.12)

有人知道如何解决这个问题吗？或者更好。如何定义具有相等列的表格并使用多列的部分内容？问题是我不知道单元格的长度。

从中删除所有 X 列意味着tabularx它永远无法做任何有用的事情，即使您避免了错误。要将文本置于 X 列的中心，请使用而\centering不是 替换。Xc

由于您指定了 T1 和 T2A 编码，因此这是使用 pdftex 而不是 luatex 处理的。
