如何删除表格中的一列

Question 1

我曾经使用过类似下面的代码。由于垂直线在此示例中效果不佳，因此我添加了不同的样式来划掉列。

它也可以划掉行，但我没有实现不同的样式。

表格删除线.tex：

    a_2={} & 95 &   0 &  0 & 0 & 20 &  0 & 35 \\
    a_3={} &100 &   0 &  0 & 0 & 25 &  0 & 40 \\
    a_4={} &150 &  25 & 50 & 0 & 75 & 35 & 90 \\
    a_5={} &140 &  15 & 40 & 0 & 65 & 25 & 80 \\
    a_6={} & 60 &   0 &  0 & 0 &  0 &  0 &  0 \\
\end{strikethroughtable}
\end{document}

这两个文件应该位于同一目录中。

我已按照以下建议格式化了表格：书签套餐（第 2 节正式餐桌的布局，第 3 页）：

如果你始终记住两个简单的指导原则，就不会犯大错：

永远不要使用垂直规则。

切勿使用双重规则。

我也用过希尼奇'S列类型来对齐数字。

您可以通过重新定义以下命令来定制视觉外观：

\strikethroughcolor
\strikethroughwidth
\strikethroughCrossWidth

或调用以下命令：

\strikethroughColumnStylePerpendicular
\strikethroughColumnStyleDiagonal
\strikethroughColumnStyleCounterdiagonal
\strikethroughColumnStyleCross

我看到你的评论说你只想划掉 $m_3=50$ 列，但我又划掉了一列，只是为了显示划掉更多列是多么容易。

请注意，我已将第一列分成两列以对齐数字，因此列索引与乍一看的不同。

在每一行上添加一些视觉效果（就像\newcolumntype{=}{@{${}={}$}}在这里添加一样）不会提供所需的输出，因为我在它出现的上方和下方添加了一个不可见的行。
