Use the first Row as header in power query

[Anonymous]

Hi, After merging some tables from different sources, I want to use the first row as headers, but only for specific columns, not all of them. Is there a way to do this? As you can see in the image, the last two columns' headers are already set.

Hi, @Anonymous 

Here's what I add to Idrissshatila's approach.
As Idrissshatila said,  before your merge Table, you can hit Use first Row as Heads in PowerQuery

Hello @Anonymous ,

So if the fields you want to do make first row as header for them are the fields before the merge, the at the right side of the power query there's a section named applied steps, so you go to the step before the merge and apply the make first row as header there before the merge step.
