如何正确调整这个tabularx中的表列参数？

Question

我正在尝试调整列参数，但找不到一个好的组合（l/ X/ p{.1\linewidth}）。X在图 1 的示例代码中添加它会使列变得非常小，我不明白这一点。因此，我X目前没有它。图 2 中没有输出最后几列的代码X

图1 不带 的输出X，图2 带 的输出X

Answer 1

我会删除所有垂直线和大多数水平线。我还会将列类型设置为右对齐，而不是完全对齐。最后，不要使用环境table——只需将“标题”放在 的参数中\frametitle。请注意，下面的代码通过设计不雇用\resizebox。

Answer 2

\begin{table}
\resizebox{\textwidth}{!}{%
  \begin{tabularx}{1.5\textwidth}{| l | X | X | X | X |} %
   ....
