Review Comment:
> This method is used to create a table. How to load the table before
creating it?
```
public void createTable(ObjectPath tablePath, CatalogBaseTable table,
boolean ignoreIfExists)
```
In the Flink SQL scenario, when users are writing SQL, this situation arises
when they use "create table if not exists" to define a table that already
exists. The parameter "ignoreIfExists" is used to ignore the existence of the
table.
