Type Parameters:

E - the element used in the table. Must implement bean-style getters for the fields

The query string is always non-null, trimmed and in lowercase.

An empty query string should result in the same value returned by totalCountSupplier

paginatedSearchFunction - a Function that returns the requested interval of (filtered) elements, sorted by the given field, in ascending/descending order. The query string is always trimmed and in lowercase. An empty query string should return the interval of all elements

fields - an array of field names of the element used in the table, in the same order of the columns

Returns:

the TableResponse instance, which should be returned to the view as a JSON response object
