javascript - How to have select filter in ngtable?

I am trying to have a select filter in ngtable. I followed this example but looks like if the select item has a space (eg: Not Installed or Not Running), then it does not work (filter). I am putting up a plunker for help.

There are couple of things I need help with

Select does not work with space in the select item.
Need exact filter match. Eg: Running select should only show Running and not Not Running.
Also in ngtable example when user clicks on the select it gives an extra blank entry which is removed once user selects and clicks the select filter again.
Auto width of ngtable w.r.t it's data.

Updated code

var app = angular.module('main', ['ngTable'])
.controller('DemoCtrl', function($scope, $filter, ngTableParams, $log) {
$scope.tableData = [{"host":"UST490","org":"00ABHI","status":"images/icon/not_installed.png","selectId":"notInstalled","name":"Not Installed"},{"host":"UST4205","org":"00ABHI","status":"images/icon/not_installed.png","selectId":"notInstalled","name":"Not Installed"},{"host":"UST4089","org":"00ABHI","status":"images/icon/not_installed.png","selectId":"notInstalled","name":"Not Installed"},{"host":"UST4492","org":"00ABHI","status":"images/icon/not_installed.png","selectId":"notInstalled","name":"Not Installed"},{"host":"Bhan-1","org":"00ABHI","status":"images/icon/not_installed.png","selectId":"notInstalled","name":"Not Installed"},{"host":"UST1102","org":"00ABHI","status":"images/icon/x_mark-red.png","selectId":"notRunning","name":"Not Running"},{"host":"UST5202","org":"00ABHI","status":"images/icon/tick.png","selectId":"running","name":"Running"}];

$scope.tableParams = new ngTableParams({
page: 1, // show first page
count: 10 // count per page
}, {
total: $scope.tableData.length, // length of data
getData: function($defer, params) {
var filterData = params.filter() ? $filter('filter')($scope.tableData, params.filter()) : $scope.tableData;
var orderedData = params.sorting() ? $filter('orderBy')(filterData, params.orderBy()) : filterData;
var table_data = orderedData.slice((params.page() - 1) * params.count(), params.page() * params.count());
params.total(orderedData.length);
$defer.resolve(table_data);
}
});

//Took help from http://ng-table.com/#/demo/3-2
/*var inArray = Array.prototype.indexOf ?
function(val, arr) {
var temp = arr.indexOf(val);
return temp;
} :
function(val, arr) {
var i = arr.length;
while (i--) {
if (arr[i] === val) return i;
}
return -1
};*/
$scope.filterAgentStatus = function(column) {
var def = $q.defer(),
arr = [],
filterAgentStatus = [];
angular.forEach($scope.tableData, function(item) {
//if (inArray(item.name, arr) === -1) {
//arr.push(item.name);
                if (jQuery.inArray(item.selectId, arr) === -1) {
                    arr.push(item.selectId);
filterAgentStatus.push({
'id': item.selectId,
'title': item.name
});
}
});
def.resolve(filterAgentStatus);
return def;
};
});

Need exact filter match

ng-table doesn't actually apply the filters the data - it's only responsible for collecting the filter values from the user.

In your getData function you've configured ng-table with, you are using the angular $filter service to apply the filter. It's this service that is responsible for doing the actual filtering. Therefore if you want an exact match behaviour you will need to use something other than $filter.

...extra blank entry which is removed once user selects and clicks the select filter again

UPDATE: I have edited my previous answer.

I've fixed this particular issue with ng-table. Here's a conversation about the problem: https://github.com/esvit/ng-table/pull/654#issuecomment-127095189

The commit for the fix: 1ee441

Auto width of ngtable w.r.t it's data.

Column widths for the rendered html table are controlled using css. ng-table does not add anything specific. You should create your own style rules to change the widths. Tip: you can also use colgroup in the html markup and assign a specific width to each <col> tag
