The Grid component supports custom data structures. In a common scenario with a simple data structure, you can associate a column with a row field using the column’s name field.
In the case of nested data structure, use the getCellValue function to calculate a column value as demonstrated below:
If you use a common value calculation algorithm for all columns, specify the getCellValue function on the Grid's level.
If editing features are enabled, you can use the editing column extension's createRowChange function to create a row changes object:
Specify the EditingState plugin's createRowChange property if you use a common algorithm for all columns.
