Power Fx function
Read and shape data
ShowColumns
Keeps only chosen columns.
What it does
The job: Take a table or data source, keep the rows you want, and reshape the columns for display.
How to use ShowColumns
Start from the task, not the alphabet. If you are shaping rows for a gallery, reach for ShowColumns alongside the other data functions in its group; if you are saving, navigating, or changing state, use it on an event such as a button OnSelect rather than in a display property. When a formula misbehaves, check for a blank value where you expected text, then confirm the behavior against the examples in the Power Fx function reference hub.
