Even when it is not used in [Mapping], there are cases where there may be impact on reading
data depending on addition position of the column. If there are any changes in the table structure, then use icon that uses this table and update the schema definition from [Update schema definition].
Since there are no links of [Update Schema Definition] in versions before 2.3, you can update
the schema definition by first selecting a different table once and later selecting it once again.
