how to filter in with a comparition between 2 fields

I want filter servers on the condition for those records with serverState and the initialstate in them are not equal.

{{servers | filter : serverState != initialState}}

You can create your own custom filter which has logic to filter the server which don't have initial state matching with initalState variable value.

Your Custom filter

myApp.filter('filterServer', function () {
  return function (servers,initialState) {
  var filteredArray=[];
  for (var k = 0; k < servers.length; ++k) {
    var server = servers[k];
    if (server.state != initialState) filteredArray.push(server);
    }
    return filteredArray;
  };
});

Your HTML

<tr ng-repeat="server in Servers | filterServer : initialState">
      <td style="width:50%;fload:left">
          <span ng-bind="server.server"></span>
      </td>
      <td style="width:40%;fload:left">
         <span ng-show="server.state==1">State 1</span>
         <span ng-show="server.state==2">State 2</span>
      </td>
    </tr>
