参考官网的代码,可以添加序号列:
$(document).ready(function() {
var t = $('#example').DataTable( {
"columnDefs": [ {
"searchable": false,
"orderable": false,
"targets": 0
} ],
"order": [[ 1, 'asc' ]]
} );
t.on( 'order.dt search.dt', function () {
t.column(0, {search:'applied', order:'applied'}).nodes().each( function (cell, i) {
cell.innerHTML = i+1;
} );
} ).draw();
} );
