  • Tabularx without any X type column does not really make sense. You may want to try replacing the c column type with X column types. – leandriis Dec 06 '21 at 18:17

    What exactly does "did not work" mean? Do you end up with a code that is not compilable, does the table still protrude into the right margin or do you end up with a table that fits but you just don't like the look of it? – leandriis Dec 06 '21 at 18:27
  • Please also make your code compilable by adding the documentclass as well as the relevant packages. (See also: minimal working example (MWE)) – leandriis Dec 06 '21 at 18:31
  • the table still in right side –  Dec 06 '21 at 18:32
  • "on right side" or "in right side" doesn't really make sense. I think you mean "is going too far to the right" or "protrudes into the right margin". – Teepeemm Dec 06 '21 at 18:58

Something like this?
