Updating a single cell value in a data table updates the rest of the cells as blank if the values for other cells are not explicitly provided

Can you please explain how to update the already existing data into the same data table with unique id with out losing the previous data if that field is not updated?

Can you please try to rephrase the question? I did not understand the ask here.
If you can explain the use case we may be able to suggest further.

I have a employee data table.now i need to update any one of the field in the employee data table.How can i do that with out losing the another fields data?

Please go through https://developer.kore.ai/docs/bots/how-tos/how-to-update-data-in-data-tables/
and https://developer.kore.ai/docs/bots/api-guide/data-update-api/

@swagata.sengupta I have the same questions. I tried the links you provided but the example says to populate all the fields.

I tried to do an update to 1 data field, but if I don’t supply all the fields for all the other columns, they will go blank. This is not like a traditional table, where you update a specific field using a unique key, and leave all the other fields untouched. Is there a way to do this? Or is this a limitation/bug?

This is a limitation currently. But it is in the roadmap to enhance the data table update feature/API.
