Good question @Greg Nolder?
If you click on the dot . that shows the Row number and Source row number on the left side of the screen, you'll see some suggestions on the right. In this data, you might wanna delete this rouge row. So choose Delete rows suggestion and Add step.
let's say row number 3 is our expected column header. So do the same mouse actions as explained above. Click the dot . and you'll see a Header transform suggestion to covert this row to header.
Notice the preview in both cases. Delete row highlights the row in red and Header transform puts the highlighted row as the data header.
Another cool thing about these suggestions are if i perform a series of mouse selections like in this case i clicked row 3 and row 1, Trifacta made a great assumption that - do i want to rename the headers based on the row values? So i can think of creating a header like col1_aa, col2_ee, col_ii etc using the first suggested transform.
Hope this helps.
Best
