Cipta jadual jquery anda sendiri plugin_jquery

Sambil meniru pemalam jadual dataGrid easyui, saya merangkumkannya sendiri. Menyedari pemuatan dinamik data json asas, paging automatik, pilih semua dan nyahpilih semua, tukar warna apabila tetikus melayang, tukar warna pada garis ganti, dsb.

Memandangkan akses ajax terlibat, ia mesti digunakan pada iis untuk melihat kesannya. Biar saya tunjukkan pemaparan dahulu:
