 ### Syntax
-When the Sequence column creates a table, an attribute is added to the property, which is used to identify the type import of `__DORIS_SEQUENCE_COL__`. The grammar design is mainly to add a mapping from the sequence column to other columns. The settings of each seed method will be described below introduce
