问题 How to group multiple columns under a single column in data table visualization Please see attached image 回答1: @BULB - You can transform your table by unpivoting and pivoting data to get the desired result. I first un-pivoted the original data table by applying transformation. INSERT > Transformations Then pivoted the unpivot output by applying another transformation. Note: You can apply both the transformations simultaneously. Final Output: 来源： https://stackoverflow.com/questions/46766637

Unfortunately, there doesn't seem to be a function like TimeOfDay.add(). Any ideas? Thanks! 回答1: You can Use Date Time for that: You can add Minutes or Hours as you like.
