While, is it needed to list all the possible interacting (two) atoms in the energygrp_table option? I have more than 3000 possible two-atom pairs, corresponding to more than 3000 table_*.xvg files.

Each atomtype probably doesn't need its own energy group. I'm busy and am going to stop making guesses based on incomplete descriptions of what you are trying to do and how you are doing it. :-)

    No text table file needs a line this long. We still don't have
    information from you, but I expect you have a malformed file.

        Dear all,

        I am trying to use tabulated potentials in my simulation.
        However, there is a limit on energygrp_table and the grompp
        reports error.

        What error?


        The interaction happens between any two of atoms, and their
        might be more than 3000 possible couples.
        What should I do to remove the limit? Thanks.

        We don't know what limit you are observing.
