columns do not have any option similar to labelFormat. Can you describe what exactly you would like to achieve with the label? I see that you already have type, data, and source so at the first glance the column looks completed.
Basically, I want to connect a handsontable instance to an API.
And for a field, I need to send to the backend an id but in the select, I should display some label.
I know that the labelFormat method doest exists, my question is, if we can manipulate/formatting the data from source.
To display not the objects…but an object field, the name or description…:
so it’s more like a key-value dropdown. Here https://jsfiddle.net/handsoncode/f0b41jug/ I have an example that works in most basic cases when you want to show a different value than the one that has to be sent to the server.
