GridPanel with two dimensions with dynamic number of rows/columns

Is it possible to create a two dimensions grid, something like https://examples1.ext.net/#/GridPane.../EditableGrid/ , but with a dynamic number of values for the header row and header column, values which are read from a store?

Something like this:
