Meanings of the various colors under column header...

akkitek · ‎09-29-2021

Hey Everyone,
Is there a documentation for the meanings of the various colors under column headers in Power Query Editor?
I am able to transform the green columns easily without any issue but even if I just use the "Remove rows" function to remove top 1 row or even if I just rename the column manually, the columns with Black lines under it become blank (image below). Any idea as to why this happens? Some times I get red & white dashed lines which mean there is an error on that column but that's usually when I add an "applied step". Looking forward to hearing from you.

@akkitek,

Check this out - https://docs.microsoft.com/en-us/power-query/data-profiling-tools

Based on the screenshot provided, You may need to try Use First Row as Header option and perform the other data transformations

Hey Siva,
Thanks for your reply. This documentation helped me understand the meaning of the colors (Dark grey means empty). However, the columns with dark grey lines under it isn't really empty. They do have values in them.

If I try to use the "Use first row as headers option" the columns become blank which is weird.

Hi @akkitek

the problem looks weird. Could you share a sample file? and we'll test it to find the cause.

Hey @v-xiaotang,
Thanks for your reply. Sure, Here's the link to the file: https://drive.google.com/file/d/1hYDaBCJQNGfp1XGeNzAxeVAbGiNlaBMX/view?usp=sharing
The error lies in the last 2 columns (column 23 & 24)
Looking forward to hearing from you thanks.
