Change the color for excel sheet that generated by writetable

Hey guys,

I am working on a function that part of it's job is to convert some tables into Excel (multisheets), this format conversion is been done with writetable command.

And now I need to change the color for part of the Excel cells, and I saw online docs that I shall communicate with windows COM server with command actxserver for this color changing option.

The point that I got stuck is that, from online docs, actxserver is not recommend to use with writetable.

So my question is that is there any possible that will allow me to modify the excel file I generated first to change the color, or shall I abandon writetable path to find some other methods to finish this conversion

Thank you
