Edit columns

Note

• For tabular formats (CSV, TSV, PSV), you can't map a column twice. To map to an existing column, first delete the new column.
• You can't change an existing column type. If you try to map to a column having a different format, you may end up with empty columns.

The changes you can make in a table depend on the following parameters:

• Table type is new or existing
• Mapping type is new or existing

Table type	Mapping type	Available adjustments
New table	New mapping	Rename column, change data type, change data source, mapping transformation, add column, delete column
Existing table	New mapping	Add column (on which you can then change data type, rename, and update)
Existing table	Existing mapping	none
