求教jquery datatables 插件如何生成一列序号列

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()

} )

var RowNumber = 0

$('#userTableContainer').jtable({

.......

fields: {

RowNumber : {

title: 'No',

display: function () {

RowNumber++

return RowNumber

}

},
