How to fill a cell in a table with two colors like a heatmap?

Question

I'm new to LaTeX. This is a similar question to How to interpolate two colors in a cell?

The relative codes from the answer is helpful @user30471: The H column type uses the collcell package to apply the command \Heat to each cell entry. However, I have over 18 columns on my table. I tried to use \begin{tabular}{ cc *18H } to create heatmap tables as that question, but might the maximum number of columns allowed in \Heat is 9. I copied the \Heat code from @user30471. And my table code is:

\begin{document}
\begin{table}[h]

\setlength{\tabcolsep}{4.2pt}

The figure is here: I'd like to get the figure like this: But it can only be up to 9 columns by:

  \Heatset{min=0,   % maximum value
           max=100,   % minimum value
           max colour=Gray0, % colour at maximum
           min colour=Snow1,      % colour at minimum
  }

How to fill in heatmap colors in \begin{tabular}{r rrrrrr rrrrrr rrrrrr} by modifying my code? Or other ways to create a similar table?

I think it is not heat map, a gradient something, the word "heat map" is confusing, specially it seems like the data has a relation with the heat map. Not a issue of your question :-). But might get a dupe-nuke from these: tex.stackexchange.com/q/174998/247020. Did you mean the gradients you would find in MS word or heatmaps as red=higher, blue=lower? — NotStanding with GoGotaHome, Oct 15 '21 at 07:43
You should put a complete working example (with 9 columns). The, we could try to see whether it works for a larger number of columns and, if not, try to solve the problem. At this time, we don't have your MWE and that's why it's difficult to help you. — F. Pantigny, Oct 17 '21 at 10:56

When the column is greater than 9, it should be \begin{tabular}{cc * {10}H} not \begin{tabular}{cc * 10H}.

Welcome to TeX.SX! A tip: You can use backticks ``` to mark your inline code as I did in my edit. – dexteritas Oct 19 '21 at 15:27
