Reverse / Manipulation Layer
Reverse the order of values within a column while maintaining all other columns. Similar to pandas' iloc[::-1] or R's rev().
For column [a,b,c,d] becomes [d,c,b,a], while other columns retain their alignment.
Common applications:
- Reverse chronological ordering
- Bottom-to-top rankings
- Descending priority assignment
- Mirror image analysis
- Backward sequence generation
- Last-to-first processing
- Inverse pattern analysis
- Alternative perspective viewing
Note: Only reverses specified column; row relationships with other columns remain intact.

columnColumn to reverse. Common scenarios:
- Sequential numbers for reverse ordering
- Timestamps for backward time analysis
- Rankings for inverse prioritization
- Measurements for reverse trending
- Categories for opposite grouping
- Scores for inverse weighting
AsColumn
nameName for the new column. If not provided, the system generates a unique name. If AsColumn matches an existing column, the existing column is replaced. The name should follow valid column naming conventions.
