The table should have the same weight as the entry on the table. It might vary depending on which palladium system you are running... It looks like maybe the 2E fantasy chart, which is 1-9 for major, 10-25 for minor, and 26+ is nothing. The weight when you create a rollable table is the number of chances of getting that result. The weight for major would be 9. The weight of minor would be 16 (25-9=16). The weight of none would be 75 (100-25=75). 75+16+9=100, which means those 3 weights add up to 100, so will give you the same chances as you would have rolling for those things with a percentile roll.
