The table form can be considered as the most universal one for setting of complex equation of state. We examine the situation when pressure and inner energy have a table view in dependence on temperature and specific volume. In the case when they are filled up by independent linear functions on the triangle cells the all functions for computing the Riemann problem can be represented in the explicit form. This allows to simplify the solution of the Riemann problems as in case of the binomial equation of state.
