  Inasmuch as the hydrostatic structure of interior neutron stars uniquely
depends on the equation of state (EOS), the inverse constraints on EOS from
astrophysical observation have been important methods to reveal the properties
of the high-density matter. Up to date, most of EOSs for neutron-star matter
are given in tabulations, but these numeric tables could be quite different in
resolution. To guarantee both the accuracy and efficiency in computing
Tolman-Oppenheimer-Volkoff (TOV) equation, a concise standard for generating
EOS tables with suitable resolution is investigated in this work. It is shown
that the EOS tables with 50 points logarithmic-uniformly located at
supra-nuclear density segment [$\rho_{0}, 10 \rho_{0} $], where $\rho_{0}$ is
the nuclear saturation density) would correspond to the interpolation-induced
errors at $\sim 0.02\%$ for the gravitational mass $M$ and $\sim 0.2\%$ for the
tidal deformability $\Lambda$.
