    const { data } = getData();

    const columns = [
        { id: "id", width: 50 },
        { id: "city", header: "City", editor: "text", width: 160 },
        {
            id: "email",
            header: "Email",
            editor: "text",
            width: 250,
            css: "center",
        },
    ];

    let api;

    $: if (api) {
        api.intercept("editor", (ev) => {
            if (ev.value.length > 15) {
                alert(`${ev.value} exceeds 15 symbols`);
                return false;
            }
        });
    }
</script>

 <Grid {data} {columns} bind:api />
