if you refer to these words of Andrew: "I'm going to include two API routines 
for computing rows and columns of the tableau in the next subversion of 
glpk", then these two routines might be:

int lpx_eval_tab_row(LPX *lp, int k, int ind[], double val[]);
/* compute row of the simplex table */

int lpx_eval_tab_col(LPX *lp, int k, int ind[], double val[]);
/* compute column of the simplex table */

see glplpx.h and the reference manual.

 good luck: gabor
