Each editable column will show a field for editing. There is a button to save or cancel all changes for the edit. The editor field can be a field instance or a field configuration and we need to provide this within the editor configuration option within the column definition. If an editor is not specified for a particular column, the cell of that column will not be editable and the value of the cell will be displayed.
