Is there a way I can reorder columns in 'Data View' within Power BI? I tried doing it in Power Query first but when the data loads into the table, the columns automatically rearrange.
I don't know that you can rearrange an existing table, but if you re-create it as a new table, you can pick the order you want.
NewTable =
SELECTCOLUMNS (
OldTable,
"Column1", OldTable[Column1],
"Column2", OldTable[Column2],
"Column3", OldTable[Column3]
)
