ngTable - 定义自定义排序次序

Question

我使用ngTable显示一些数据，我需要排序顺序在页面加载，以显示它的初始方式。有正常的选项来设置排序，例如sorting: {color: "asc"}，这将按字母顺序排列color列。假设这是我的表中的数据：

var x = [ 
    {name: "allen", age: 33, color:"green"}, 
    {name: "jon", age: 23, color:"blonde"}, 
    {name: "silver", age: 54, color:"yellow"}, 
    {name: "james", age: 52, color:"grey"}, 
    {name: "flint", age: 25, color:"pink"}, 
    {name: "billy", age: 31, color:"blonde"}, 
    {name: "bones", age: 47, color:"grey"}, 
    {name: "michael", age: 35, color:"green"}, 
    {name: "jackson", age: 234, color:"yellow"}, 
    {name: "leonardo", age: 12, color:"brown"}, 
    {name: "dicaprio", age: 73, color:"pink"}, 
    {name: "sylvester", age: 35, color:"blonde"} 
]; 

我如何通过自定义指令设置的color列的初始排序顺序，比如首先​​，那么所有pink那么所有yellow和最后grey。 这是我到目前为止的代码：

function demoController(NgTableParams, simpleList) { 
     var names = [ 
     {name: "allen", age: 33, color:"green"}, 
     {name: "jon", age: 23, color:"blonde"}, 
     {name: "silver", age: 54, color:"yellow"}, 
     {name: "james", age: 52, color:"grey"}, 
     {name: "flint", age: 25, color:"pink"}, 
     {name: "billy", age: 31, color:"blonde"}, 
     {name: "bones", age: 47, color:"grey"}, 
     {name: "michael", age: 35, color:"green"}, 
     {name: "jackson", age: 234, color:"yellow"}, 
     {name: "leonardo", age: 12, color:"brown"}, 
     {name: "dicaprio", age: 73, color:"pink"}, 
     {name: "sylvester", age: 35, color:"blonde"} 
    ]; 
    this.tableParams = new NgTableParams({ 
     // initial sort order 
     sorting: { color: ["green","pink","yellow","grey"] } 
    }, { 
     dataset: names 
    }); 
    }

你有没有在指令添加的那种属性？

<td title="'Name'" filter="{ name: 'text'}" sortable="'name'">
