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. For instance, comparing Column 1 against Column2 might yield 4 matches. The yellow, bold outlined cells are the matches. And here's how I count them: I'm thinking there might be an 'easy' way to accomplish this using Power

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. This can be done by using the following formula in Excel. I need something similar but then in M. Date = DATE([year],1,-2)-WEEKDAY(DATE([year],1,3))+[week]*7 + [day]-1 For example: Week 2, Day 3, Year 2019 should be: 9-1-2019 (In #dd-mm-yyyy#) Thanks in advance 回答1: This will do it = Table.AddColumn(Source, "Custom", each Date.From(Number.From

So probably you are using the function in an environment where it is not yet available. If I

问题 I have a link of a website from where I want to pull out data through power query. Every time, this link will get changed as per need. So I need to use power query every time.

问题 I'm thinking this has to have a simple answer, but I can't find any examples. I have to compare every member of a list to a list of substrings to see if that member contains a substring, and if it does - return the substring to a third list at the same position as the member of the first list. 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
