Do not display the splits parameter in Rang

[SQL]

explain extended select * from range(0, 4);

plan

== Parsed Logical Plan ==

'Project [*]

+- 'UnresolvedTableValuedFunction [range], [0, 4]

== Analyzed Logical Plan ==

id: bigint

Project id#11L

+- Range (0, 4, step=1, splits=None)

== Optimized Logical Plan ==

Range (0, 4, step=1, splits=None)

== Physical Plan ==

*(1) Range (0, 4, step=1, splits=1)

The splits parameter will only be set during the physical execution phase. But it is also displayed in the logical execution phase as None, which is not very user-friendly. Showing the physical execution plan can help users.
