    Since you have some responses for your other questions that seem to answer your question, please consider marking one of them as ‘Accepted’ by clicking on the tickmark below their vote count (see How do you accept an answer?). This shows which answer helped you most, and it assigns reputation points to the author of the answer (and to you!). It's part of this site's idea to identify good questions and answers through upvotes and acceptance of answers. – Kurt Feb 11 at 5:11

  • What did you change? I can compile with my current MiKTeX the last answer without error messages or warnings. Which tex distribution do you use, which version number? Please do not only throw code at us, explain exactly what you are doing and what happens. – Kurt Feb 11 at 5:18

Well, you added a wrong definition of \cellcolor[HTML]{cyan!30} in your last line of the table. Correct it to:

\multicolumn{14}{l|}{\cellcolor{cyan!30}}
