双列环境中的 supertabular

Question

我写了一个文档，它代表了一些东西的目录。大部分内容是一个长表，表头位于两个平衡的列中。xelatex用于构建 pdf。

longtabu我计划使用禁忌但似乎与multicols和不兼容在 LaTeX 中平衡多列内的长表不支持解决方案标头。

所以目前我supertabular使用使用新命令将 Supertabular 转换为 Multicols。它运行良好，但第一页看起来不正确。第一列未完全填充：

此外，如果删除标题，它不会填充所有页面上的两列：

为什么会发生这种情况以及如何解决？

我不熟悉 TeX lang，所以很难理解为什么这两列技巧有效。

我曾尝试过longtable、xtab和。并且比其他tabu方法更适合这项任务。supertabularsupertabular

如果该问题无法通过 supertabular 解决，那么也许还有其他支持标题、分页符和多列环境（基本上是两列）的表格包？

谢谢！
