We do have the table to support cast between data types but not fully tested. The goal of this issue is to track the support and test status of all cast cases.

Just updated the list.
Description
Not any pair of types can be converted from each other. Spark has a check here. Gluten cpp has some pre-check logic for cast expression. See Gluten code here.
This is the output from a tool proposed by https://github.com/apache/incubator-gluten/pull/6392 ("!!" marks not supported cast case).
