Ngtable：需要显式表头并选择过滤器
我需要显示一个5列表数据，其中3列标题类似于下面的屏幕截图（请igonre表格主体中的第1列用黄色星号）。
帮助我解决下面给出的几个问题。
- 当我在thead中提供显式标头值以为
last 3 runs执行3的colspan时，我没有获得过滤器。 - 使用
filterStatusFor0($column)，filterStatusFor1($column)＆amp;进行选择过滤是否正确/最好？我的代码中有filterStatusFor2($column)？
ngtable
<div class="col-md-8">
<table ng-table="taskDetailTableParams" show-filter="true" class="table upgradeTaskDetailTable text-left table-bordered">
<thead>
<th>Task Name</th>
<th>Type of Task</th>
<th colspan="3">Last 3 runs</th>
</thead>
<tbody>
<tr ng-repeat="item in $data" height="10px" class="animate" ng-animate="{enter: 'animate-enter', leave: 'animate-leave'}">
<td data-title="'Task Name'" class="text-left col-sm-4 col-md-4 col-lg-4" header-class="text-left" filter="{ 'name': 'text' }" sortable="'name'">{{ item.name }}</td>
<td data-title="'Type of Task'" class="text-left col-sm-2 col-md-2 col-lg-2" header-class="text-left" filter="{ 'type': 'text' }" sortable="'type'">{{item.type}}</td>
<td data-title="'latest Run'" class="text-left col-sm-2 col-md-2 col-lg-2" header-class="text-left" filter="{ 'selectIdFor0': 'select' }" sortable="'selectIdFor0'" filter-data="filterStatusFor0($column)"><img ng-src="{{ item.statusImageFor0 }}" title="{{ item.statusFor0 }}" data-toggle="tooltip" data-placement="bottom" /></td>
<td data-title="'2nd Latest Run'" class="text-left col-sm-2 col-md-2 col-lg-2" header-class="text-left" filter="{ 'selectIdFor1': 'select' }" sortable="'selectIdFor1'" filter-data="filterStatusFor1($column)"><img ng-src="{{ item.statusImageFor1 }}" title="{{ item.statusFor1 }}" data-toggle="tooltip" data-placement="bottom" /></td>
<td data-title="'3rd Latest Run'" class="text-left col-sm-2 col-md-2 col-lg-2" header-class="text-left" filter="{ 'selectIdFor2': 'select' }" sortable="'selectIdFor2'" filter-data="filterStatusFor2($column)"><img ng-src="{{ item.statusImageFor2 }}" title="{{ item.statusFor2 }}" data-toggle="tooltip" data-placement="bottom" /></td>
</tr>
</tbody>
</table>
</div>
选择过滤器代码
$scope.filterStatusFor0 = function(column) {
var def = $q.defer(),
arr = [],
filterStatus = [];
angular.forEach($scope.taskDetailData, function(item) {
if (jQuery.inArray(item.selectIdFor0, arr) === -1) {
arr.push(item.selectIdFor0);
filterStatus.push({
'id': item.selectIdFor0,
'title': item.statusFor0
});
}
});
filterStatus.sort(function(a, b) {
if (a.id < b.id)
return -1;
if (a.id > b.id)
return 1;
return 0;
});
def.resolve(filterStatus);
return def;
};

您可以添加带有template-header="my_header.html"的自定义标头作为direcitve属性，然后获取colgroup的最简单方法是在正常标头模板上方添加一行。
所以更容易将所有过滤器放在适当位置，对于该行中的其他空单元格，您可以执行css样式以移除边框以获得更好看的表格。 （未在更新的plunkr中添加。）
对于问题的第二部分，使用过滤方法。你重复了三次相同的代码（不遵循DRY原则）。
您可以通过在函数中添加id来改善这一点，这样您就只能使用一个仅使用不同ID调用的过滤方法。
以下是添加了自定义标题模板的更新代码。您还可以在此plunkr中找到代码。
