Question

我正在尝试使用Angular 6访问ag-grid上的单个单元格。html看起来像这样：

 <ag-grid-angular 
 style="width: 700px; height: 200px;" 
 class="ag-theme-balham"
 [rowData]="rowData" 
 [columnDefs]="columnDefs"
 rowSelection="single"
 colDef.editable=true
 (gridReady)="onGridReady($event)"
 >
 </ag-grid-angular>

打字稿类是：

 ngOnInit( ) {

  }
  onGridReady(params){
    this.gridApi = params.api
    this.columnApi =  params.columnApi
  }
  updateRow(){
    var rowNode = this.gridApi.getRowNode(0);
    rowNode.setData(
      { make: 'changed', model: 'changed', price: 10 },
    )

  }
  updateCell(){
    var rowNode = this.gridApi.getRowNode(0);
    this.gridApi.getRowNode(0)
    rowNode.setDataValue("model","mobile")
  }
  addColumn(){
    var rowNode = this.gridApi.getRowNode(0);
    var x = parseInt(rowNode.data.price)
    var rowNode = this.gridApi.getRowNode(1);
    var y = parseInt(rowNode.data.price)
    var rowNode = this.gridApi.getRowNode(2);
    var z = parseInt(rowNode.data.price)
   console.log("price", x ,y, z)
   this.total = x+y+z


  }

  columnDefs = [
   // use this for the whole column   {headerName: 'Make', field: 'make',cellStyle: {  'border-bottom': '3px double'} },
   {headerName: 'Make', field: 'make',cellStyle: {
    // you can use either came case or dashes, the grid converts to whats needed
    backgroundColor: '#aaffaa' // light green
}},
    {headerName: 'Model', field: 'model'},
    {headerName: 'Price', field: 'price', editable: true},
    {headerName: '', field: '', editable: true}
];

rowData = [
    { make: 'Toyota', model: 'Celica', price: 35000, cellClass: "col-1" },
    { make: 'Ford', model: 'Mondeo', price: 32000 },
    { make: 'Porsche', model: 'Boxter', price: 72000 }
];

我可以使用cellstyle定位列，但我只想向每个单元格添加边框。是否有可能像我一样使用以下方法来定位细胞：

var rowNode = this.gridApi.getRowNode(1);

并向rowNode添加样式，或者还有另一种方法可以实现这一点？

Answer 1

根据documentation，您应该可以通过如下所示传递参数将样式应用于单个单元格，或者可以使用cellClassRules。

  columnDefs = [
   // use this for the whole column   {headerName: 'Make', field: 'make',cellStyle: {  'border-bottom': '3px double'} },
   {headerName: 'Make', field: 'make',cellStyle:function(params) {
    // you can use either came case or dashes, the grid converts to whats needed
//Style the specific cell with one class and the whole column with another
return (params.colDef===1?'my-class-1':'my-class-2');
}},
    {headerName: 'Model', field: 'model'},
    {headerName: 'Price', field: 'price', editable: true},
    {headerName: '', field: '', editable: true}
];

Answer 2

我发现如果我使用这个

{headerName: 'Model', field: 'model',cellClass:function(params) {
  console.log("params ", params);
  console.log("params value", params.value);
  console.log("params colDef", params.node.rowIndex);
  // you can use either came case or dashes, the grid converts to whats needed
//Style the specific cell with one class and the whole column with another
return (params.node.rowIndex===1?'my-class-1':'my-class-2')}},

，您需要将css放在styles.css中，因为它在组件css文件中不起作用。我可以定位单个单元格。

如果只想在每个单元格上添加边框，则可以使用简单的CSS解决方案-

.ag-cell {
    border: solid 1px blue !important;
}

如果只想为所选单元格添加边框，则可以使用-

 .ag-cell-focus {
        border: solid 1px blue !important;
    }

使用ng-grid和Angular 6设置单个单元格的样式
