Complex solution to work with pageable data, including sorting, filtering, actions, changing displayed columns, etc.

import { defaultGetter } from '../FieldModel';
export default function localSort(itemModel, data, sort) {
    if (!sort)
        return data;

    var actualSortBy = __spreadArray([], __read(sort));
    actualSortBy.reverse();
    actualSortBy.forEach(function (_a) {
        var field = _a.field, direction = _a.direction;
        var fieldModel = itemModel.fields.find(function (_a) {
            var key = _a.key;
            return key === field;
        });
        if (!fieldModel)
            throw Error("Missing field " + field + " model in item model");
        inplaceSort(itemModel, result, fieldModel, direction);
    });
    return result;
}
function inplaceSort(itemModel, src, fieldModel, direction) {
    if (direction === void 0) { direction = 'ASC'; }
    var getter = fieldModel.getter || defaultGetter;
    var ascComparator = function (a, b) {
        var vA = getter(a, fieldModel, itemModel);
        var vB = getter(b, fieldModel, itemModel);
        if (vA === undefined && vB === undefined)
            return 0;
        if (vA === undefined && vB !== undefined)
