I have only a single thac0 table, which looks nothing like the original
(stock) table. My thac0 is an integer array; there is a single element
in the table for each class - here's what it looks like:

const int thaco[NUM_CLASSES] = {
        LVL_IMMORT * 1.3,       /* mage */
        LVL_IMMORT * 1, /* cleric */
        LVL_IMMORT * .95,       /* thief *
        LVL_IMMORT * .85        /* warrior */
};

What it defines is the level at which thac0 for the class is 1. (It is
assumed that level 1 for every class has a thac0 of 20.)

With this, in (i think it was fight.c), where the initial value of
calc_thaco was originally pulled from a table, I assign it as follows:

        calc_thaco - MAX(1, ((-19 / thaco[(int) GET_CLASS(ch)]) *
                GET_LEVEL(ch)) + 20);

This (unless I've messed up the math) spreads thac0 out from 20 to
1 linearly, with a slope based on the table above, and clips the bottom
end at 1.
