本文档展示了如何在ag-grid表格库中使用vue实现单元格右键菜单，并动态改变选中单元格的样式。通过监听`onCellContextMenu`事件，自定义右键菜单项并更新单元格样式。同时，文中提供了完整的代码示例，包括创建数据、定义列定义、以及单元格点击和聚焦事件处理。

在这里插入图片描述

你在看这篇文章的时候，那就说明你项目中已经引入了ag-grid表格库，本文是基于 vue 实现的。

<ag-grid-vue :style="{height: tableHeight,width: '100%'}" class="flex-grow-1 flex-shrink-1 ag-theme-alpine"
								 :gridOptions="gridOptions"
								 :columnDefs="columnDefs"
								 :rowData="rowData"
								 :sideBar="sideBar"
								 :animateRows="true"
								 :autoGroupColumnDef="autoGroupColumnDef"
								
								 :defaultColDef="{
									sortable: true,
									resizable: true,
									filter: true,
									minWidth: 100,
								 }"

								 
								 :groupHeaders="true"
								 :suppressRowClickSelection="true"
								 rowSelection="multiple"

								 :allowContextMenuWithControlKey="true"

								 @grid-ready="onReady"
								 @cell-clicked="onCellClicked"
								 @cell-context-menu="onCellContextMenu"

首先定义两个全局变量，注意放在 export default语句外边

let selectRow = null,selectColumn = null

export default {
    data(){
        return {
            gridOptions: null,
            gridapi: null,
            columnDefs: null,
            rowData: null,
            showGrid: false,
            sideBar: false,
            rowCount: null,
            autoGroupColumnDef: null,
           
        }
    },
    methods: {
        //数据是模拟   不必太在意于
         createRowData() {
                const rowData = [];

                for (let i = 0; i < 200; i++) {
                   
                    rowData.push({
                        name: '张三'+i,
                        skills: {
                            android: Math.random() < 0.4,

                            windows: Math.random() < 0.4,
                            css: Math.random() < 0.4
                        },
                        dob: '张三'+i,
                        address: '张三'+i,

                        country: '张三'+i,
                        continent: '张三'+i,
                        language: 'zh',
                        mobile: 134884552+'i',
                        landline: '张三'+i
                    });
                }

                this.rowData = rowData;
            },
