Live typing cells validation and restriction

Hello everyone, i have been looking for a good library to start a project and handsontable looks like my best option to… but, specifically in validation, i don’t know if is possible to validate and restrict cells while users are typing with this library…

Example:
If i need a field “CURP” which is composed this way:
4 letters, 4 numbers, 6 letters and 2 numbers, i would be able to firstly type “ABCD”, but if i type "ABCD E " cell would’t let me continue typing, and actual value should still “ABCD” and continiously, “ABCD1234” but no "ABCD1234 5 " etc etc. (sorry about the spaces, strong text feature didn’t work without them)

I appreciate your answers, thanks! :smile:

Hi @alire.eduardo

validator is called when an editor is already closed so to restrict some chars or a logic of typing you’d need to create a custom editor. Unless you can agree on leaving an old value when typed one doesn’t meet the cell’s requirement. Then this demo may come in handy.
