Hello @TechnicalSupport,
thank you for your help, it's much appreciated. The Worksheet file you send me contains a beautiful table that would be perfect for my work:

However, it sadly doesn't show up on the LaTeX (File > Export As > LaTeX) generated PDF: Maple_Test.pdf.

Is there a way to have it generated as LaTeX or add Lines to the Matrix to make it easier to read?
Thank you very much for your help, if it's not possible I'll work around the limitation.
