Column API
Description
getColumns
Retrieve the columns from the table
addColumn
Add a column to the table
updateColumn
Update the properties of a column to the table
removeColumn
Remove a column from the table
batch
The changes will post together in the batch mode
And the column remote APIs could be handled by the self-defined functions which are similar as the Handle Requests.
Request and Response
Operation
Request Data
Response Data
getColumns
None
Column[]
addColumn
ColumnWithDefaultData
ColumnData
updateColumn
ModifiedColumnData
ModifiedColumnData
removeColumn

ColumnData
batch
BatchItemData[]
BatchResultData[]
The Commands
Besides defining through UI, there are also the commands to define the columns:
DefineColumn
The DefineColumn command could add a column:
ModifyColumn
The ModifyColumn command could change the column properties:
RemoveColumn
The RemoveColumn command could remove the column:
/*REPLACE_MARKER*/
