我尝试使用以下方法在UI-Grid的列标题级别实现多列分组.
我遵循的步骤:
包含UI网格的下面标题单元格模板,以及另一个"UI网格行":
<div class="ui-grid-header custom-ui-grid-header">
<div class="ui-grid-top-panel">
<div class="ui-grid-header-viewport">
<div class="ui-grid-header-canvas">
<div class="ui-grid-header-cell-wrapper" ng-style="colContainer.headerCellWrapperStyle()">
<div class="ui-grid-header-cell-row">
<div class="ui-grid-header-cell" ng-repeat="superCol in grid.options.superColDefs track by $index" col-name="{{superCol.name}}">
<div class="ui-grid-cell-contents" data-ng-bind="superCol.displayName">
</div>
</div>
</div>
<div class="ui-grid-header-cell-row">
<div class="ui-grid-header-cell ui-grid-clearfix" ng-repeat="col in colContainer.renderedColumns track by col.colDef.name" ui-grid-header-cell super-col-width-update col="col" render-index="$index">
</div>
</div>
</div>
</div>
</div>
<div ui-grid-menu></div>
</div>
</div>

$scope.gridOptions = {
headerTemplate: 'views/header-template.html',
superColDefs: [{
name: 'group1',
displayName: 'Group 1'
}, {
name: 'group2',
displayName: 'Group 2'
}],
columnDefs: [{
name: 'name',
displayName: 'Name',
superCol: 'group1'
}, {
name: 'title',
displayName: 'Title',
superCol: 'group1'
}, {
name: 'age',
displayName: 'Age',
superCol: 'group2'
}],
data: [{
name: 'Bob',
title: 'CEO',
age: '31'
}, {
name: 'Frank',
title: 'Lowly Developer',
age: '33'
}]
};

指示:
.directive('superColWidthUpdate', ['$timeout', function ($timeout) {
return {
'restrict': 'A',
'link': function (scope, element) {
var _colId = scope.col.colDef.superCol,
_el = jQuery(element);
_el.on('resize', function () {
_updateSuperColWidth();
});
var _updateSuperColWidth = function () {
$timeout(function () {
var _parentCol = jQuery('.ui-grid-header-cell[col-name="' + _colId + '"]');
var _parentWidth = _parentCol.outerWidth(),
_width = _el.outerWidth();
_parentWidth = ((_parentWidth === 1) ? 0 : _parentWidth) + _width + 'px';
_parentCol.css({
'min-width': _parentWidth,
'max-width': _parentWidth
});
}, 0);
};
_updateSuperColWidth();
}
};
}]);

在上面的方法中,解决方案是通过操纵DOM来呈现新的标题行和新的标题单元格来实现的,这些标题单元格位于通常的标题行之上,但位于标题视口中.
但是,我正在寻找任何更好的方法,可能是通过使用UI-Grid的内部服务或指令.这里的任何帮助非常感谢!

有一个更简单的解决方案。编写一个customTreeAggregationFn,仅计算您希望包含在分组行中的行的标识:
var customTreeAggregationFn = function(aggregation, fieldValue, value, row) {
// calculates the average of the squares of the values
if (typeof(aggregation.count) === 'undefined') {
aggregation.count = 0;
}
aggregation.count++;
aggregation.value = value;
}

然后使用此函数并过滤掉 cellTemplate 中的非标题行:
{
name: 'EDM Id',
displayName: 'EDM Id',
field: 'Entity__r.EDM_ID__c',
enableColumnMenu: false,
customTreeAggregationFinalizerFn: function(aggregation) {
aggregation.rendered = aggregation.value;
},
cellTemplate: '<div><div class="ui-grid-cell-contents" ng-if="row.groupHeader" title="TOOLTIP">{{COL_FIELD CUSTOM_FILTERS}}</div></div>',
customTreeAggregationFn: customTreeAggregationFn
}
