***Test Failed*** 1 failures.
```
@Eric5553 can you fix the pyspark test? you should update `dataframe.py` `explain` method
```
>>> df.explain(mode="formatted")
== Physical Plan ==
* Scan ExistingRDD (1)
(1) Scan ExistingRDD [codegen id : 1]
Output: [age#0, name#1]
.. versionchanged:: 3.0.0
Added optional argument `mode` to specify the expected output format of plans.
