我有下表，它使用Ssiunitx 的列类型。代码如下所示。
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？

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

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。
- 可用的
- 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。
