我试图像这样从我的ag-Grid删除一行：
let alertRow : RowNode = this.gridApi.getRowNode(rowIndex);
console.log(alertRow);
this.gridApi.updateRowData({remove: [alertRow]});
它给了我这个错误：
ag-Grid：找不到数据项，因为找不到对象
我可以在控制台中看到RowNode是正确的节点并存在。我还可以使用updateRowData()来添加新行，但是尝试删除会出现此错误。
我正在Angular 6组件中使用ag-Grid。
为什么删除无效？
答案 0 :(得分：1)
用
代替updateRowData({remove:[alerRow]})
updateRowData({remove:[alertRow.data]}))

不能完全确定这是添加到un.spike's answer的正确位置/方式，但是如果您使用getSelectedNodes方法来获取要删除的数据，则语法为稍有不同（需要索引到选定的节点）。
（均假设您使用的是单行选择）

而且，为了“完整性”，
getSelectedRows （即使API建议使用const selectedNode = this.gridApi.getSelectedNodes();
this.gridApi.updateRowData({ remove: [selectedNode[0].data] });
）
getSelectedNodes答案 2 :(得分：0)
如果使用vue.js，则可以使用以下代码行：
获取选择的行const selectedRow = this.gridApi.getFocusedCell()
通过选择行const node = this.gridApi.getRowNode(selectedRow.rowIndex)
ApplyTransaction通过节点的数据删除该节点。 this.gridApi.applyTransaction({ remove: [node.data] })
