jquery - Knockout with DataTables on HTML Table -


i have html table works fine without datatables.

however, want implement datatables can use filtering/search functionality , add/remove columns.

how working knockout?

var viewmodel = function() {    $('#mytable').datatable({          ajax: {              url: this.taskrecords()          }      });    this.taskrecords = ko.observablearray([  {  	entitycode: "name",    entityname: "name desc23",    tagname: "l1",    tasklist: [    	{      	taskname: "taskabc",        taskrecordlist: [        	{           	statusflagname: "ok"          },          {           	statusflagname: "test"          }        ]      },      {      	taskname: "taskdef",        taskrecordlist: [        	{           	statusflagname: "error"          }        ]      }    ]  }  ]);      };  ko.applybindings(new viewmodel());

problem

it looks trying bind data twice:

  1. with knockout in html
  2. with datatable ajax url

and there problem: datatable not add table columns without corresponding header.

solution

i got work 2 modifications:

a. no data binding datatable, init with:

$('#mytable').datatable({  responsive: true });

b. add <th>tasks</th> table header
