I am unable to reproduce the problem here (LyX 2.1.4 on Linux Mint 17.2); the document compiles correctly (with a gray table row) the first time, with no error messages. Most likely you are inserting the ERT in the designated row in a place that offends LaTeX's sensibilities. If you can post a minimal example, perhaps someone can diagnose it.
