根据单元格值为列着色

tag-icon • tag-icon tables color siunitx collcell
根据单元格值为列着色

我有下表，它使用Ssiunitx 的列类型。代码如下所示。

在此处输入图片描述

我想根据单元格值为第四列和最后一列着色，即值越大，单元格颜色越深，忽略 0 和标题。我尝试定义一种新的列类型，P如下所示：

\newcommand*{\colorfromval}[3]{\cellcolor{blue!\numexpr (#3-#1)/(#2-#1)\relax}#3}
\newcolumntype{P}[2]{>{\collectcell{\colorfromval{#1}{#2}}}S<{\endcollectcell}}

使用collcell包。但是，这不起作用。当在第二列（用于测试）上使用列类型时P{0.9}{1.2}，我收到错误Forbidden control sequence found while scanning use of \collectcell.。

我怎样才能做到这一点？

答案1

看起来S列类型与冲突\collectcell，所以我使用它的命令版本\tablenum。

注意，现在需要使用\multicolumn{1}{l}{...}来消除新列类型的影响T。参见第一行中的示例。

更新（2023-10-08）

  • 新语法P{<value-to-color options>}{<siunitx options>}。
    • 可用的<vtoc options>有min=<num>、、、max=<num>和first color=<color>。second color=<color>
    • first color=white, second color=blue已初步设定。
    • 最小值和最大值分别映射到第一和第二种颜色，任何等于的值<min> + <factor> * (<max> - <min>)都映射到颜色<second color>!<ratio>!<first color>，其中<factor>在范围[0, 1]和之间<ratio> = <factor> * 100。
  • 不要为P列中的空单元格着色。
  • 对给定范围之外的值进行标准化[min, max]。
  • 使用更精确的\fpeval（浮点数评估）来计算色彩比例。
