Neither does … WebFine print: some chi-square lookup tables have many columns, one for each p-value you might be interested in. In that case, you first need to find the 0.05 p-value (or any other p-value you're asked for), then the df, then the chi-square-crit. Even finer print: or, you may be asked to find the p-value corresponding to the chi-square-calc.
