问题 Given this table: I'd like to derive this table: ... sort of like a mileage chart in a map book. I'm trying to create a cross-table comparison of the words in each of the columns, against all of the other columns' words, to show how many matches there are between them.

问题 I want to create an extra column to my dataset. This needs to be done by using M in PowerQuery. I have the weeknumber, dayoftheweek and year available.

Example: ListA = {"help me rhonda", "in my room", "good vibrations", "god only knows"} ListB = {"room", "me", "only"} ListC should then should = {"me", "room", null, "only"} I'm an advanced programmer
