Review comment:
Yep, that means for now, we only allow:
```python
withColumns({"col1": col1, "col2": col2})
```
in future, we can also enable kwargs to allow:
```python
# With args and kwargs
withColumns({"col1": col1, "col2": col2}, col3=col3)
# With only kwargs
withColumns(col4=col4)
```
If no objection, I will update to *colsMap in this PR.
