sort descending with multiple columns

[Sreekanth Jella]

Hi,

I'm trying to sort multiple columns and column names are dynamic.

df.sort(colList.head, colList.tail: _*)


But I'm not sure how to sort in descending order for all columns, I tried
this but it's for only first column..

df.sort(df.col(colList.head).desc)
How can I pass all column names (or some) with descending order.


Thanks,
Sreekanth
