this update table supplied json...

http://jsfiddle.net/archersfiddle/eemxvu0z/

html

<table id="mytable">     <tr class="head">         <th></th>         <th>new york</th>         <th>chicago</th>         <th>san francisco</th>     </tr>     <tr>         <th>blabla</th>         <td>sat, 4 feb 2012<br />11am - 2pm</td>         <td>sat, 3 mar 2012<br />11am - 2pm</td>         <td>sat, 17 mar 2012<br />11am - 2pm</td>     </tr> </table>

javascript

var data = json.parse(eventsjson);  function showevent(id) {     (var in data.events.event) {         if (data.events.event[i].id == id) {             var thisevent = data.events.event[i];             var head = "<tr class=\"head\"><th></ht>";             var row = "<tr><th>" + thisevent.name + "</th>";             (var l in thisevent.locations) {                 var thislocation = thisevent.locations[l];                 head += "<th>" + thislocation.location + "</th>";                 row += "<td>" + thislocation.eventdate + "<br/>" + thislocation.eventtime + "</td>";             }             head += "</tr>";             row += "</tr>";             $("#mytable").html(head + row);         }     } }  showevent(4);  // example

basically, rebuild html table supplied data , use $("#mytable").html(html); update it. expect you'll using event, such select value change, trigger table update, use showevent(id); function call update it.
