Re: [Groff] Tables in .ig/.. blocks not ignored

[Tadziu Hoffmann]

It works if you use ".ig xx" paired with ".xx" (substitute some
reasonable name for xx if you like; make sure its defined as a
no-op).

Explanation: this is like nested definitions,

  .de xx
  .de yy
  hello
  \\..
  ..

where you have to "hide" the inner terminating "..", so that
when defining xx it will not be seen. ".ig" works the same as
".de", and your problem is that tbl itself includes some macro
definitions in the code it inserts in your document. Since you
have no way of hiding the definition terminations inside the tbl
code, you can use the alternative method,

  .de xx zz
  .de yy
  hello
  ..
  .zz
