快速开发网站惠州附近公司做网站建设多少钱

1、上个图，要实现这样的：

Vxe Table v4.6 官方文档

2、使用 row-config.isCurrent 显示高亮行，当前行是唯一的；用户操作点击选项时会触发事件 current-change

<template><div><p><vxe-button @click="selectRowEvent">设置第二行选中</vxe-button><vxe-button @click="clearSelectEvent">取消选中</vxe-button><vxe-button @click="getCurrentEvent">获取高亮行</vxe-button></p><vxe-tableborderref="tableRef"height="300":row-config="{isCurrent: true, isHover: true}":data="tableData"@current-change="currentChangeEvent"><vxe-column field="name" title="Name"></vxe-column><vxe-column field="sex" title="Sex"></vxe-column><vxe-column field="age" title="Age"></vxe-column><vxe-column field="address" title="Address" show-overflow></vxe-column></vxe-table></div>
</template><script lang="ts" setup>
import { ref } from 'vue'
import { VXETable, VxeTableInstance, VxeTableEvents } from 'vxe-table'interface RowVO {name: stringrole: stringsex: stringage: numbercontent: string
}const tableRef = ref<VxeTableInstance<RowVO>>()const tableData = ref<RowVO[]>([{ name: 'Test1', role: 'Develop', sex: 'Man', age: 28, content: 'test abc' },{ name: 'Test2', role: 'Test', sex: 'Women', age: 41, content: 'Guangzhou' },{ name: 'Test3', role: 'PM', sex: 'Man', age: 32, content: 'Shanghai' },{ name: 'Test4', role: 'Designer', sex: 'Women', age: 24, content: 'Shanghai' }
])const currentChangeEvent: VxeTableEvents.CurrentChange<RowVO> = ({ rowIndex }) => {console.log(`行选中事件 ${rowIndex}`)
}const selectRowEvent = () => {const $table = tableRef.valueif ($table) {$table.setCurrentRow(tableData.value[1])}
}const clearSelectEvent = () => {const $table = tableRef.valueif ($table) {$table.clearCurrentRow()}
}const getCurrentEvent = () => {const $table = tableRef.valueif ($table) {VXETable.modal.alert(JSON.stringify($table.getCurrentRecord()))}
}
</script>

3、设置的时候，加上这个设置就可以了

 :row-config="{ isCurrent: true,  isHover: true}"
