Jiayi Liu updated SPARK-49519:
------------------------------
Description:
Currently, the subclass of {{FileTable}} only uses the options from relation
when constructing the {{{}FileScanBuilder{}}}, which leads to the omission of
the contents in {{{}FileTable.options{}}}. For the {{{}TableCatalog{}}}, the
{{dsOptions}} can be set into the {{FileTable.options}} returned by the
{{TableCatalog.loadTable}} method. If only the relation options are used here,
the {{TableCatalog}} will not be able to pass {{dsOptions}} that contains table
options to {{{}FileScan{}}}.
Merge the two options is a better option.

Currently, the {{CSVTable}} only uses the options from {{relation}} when
constructing the {{{}CSVScanBuilder{}}}, which leads to the omission of the
contents in {{{}CSVTable.options{}}}. For the {{{}TableCatalog{}}}, the
{{dsOptions}} can be set into the {{CSVTable.options}} returned by the

Combining the two options is a better option.
