vue3封装Element Plus table表格组件

支持绝大部分Element Plus原有设置属性，支持分页，支持动态适配高度

效果展示

组件代码：

javascript"><template><div class="table-wrap" ref="tableWrap"><el-tableclass="w100 h100":data="tableInfo.tableData":height="tableHeight"v-bind="attrs"><!-- 动态生成列 --><template v-for="(item, index) in columns" :key="index"><!-- 选择列 --><el-table-columnv-if="item.type == 'selection'"type="selection"v-bind="item"></el-table-column><!-- 普通列 --><el-table-column v-else-if="!item.subColumns" v-bind="item"><template #default="scope"><slot :name="item.prop" :scope="scope">{{ scope.row[item.prop] }}</slot></template></el-table-column><!-- 嵌套列 --><el-table-column v-else v-bind="item"><el-table-columnv-for="(child, childIndex) in item.subColumns":key="childIndex"v-bind="child"><template #default="scope"><slot :name="child.prop" :scope="scope">{{ scope.row[child.prop] }}</slot></template></el-table-column></el-table-column></template></el-table><el-pagination:page-sizes="pageSizes":current-page="page.currentPage":page-size="page.pageSize"backgroundlayout="total, sizes, prev, pager, next, jumper":total="tableInfo.total"@size-change="handleChangePage({currentPage: page.currentPage,pageSize: $event,})"@current-change="handleChangePage({currentPage: $event,pageSize: page.pageSize,})"/></div>
</template><script setup>
import { ref, onMounted, onUnmounted } from "vue";// Props 接收
const { tableInfo, columns, pageSizes, ...props } = defineProps({tableInfo: {type: Object,default: () => {return {tableData: [],total: 0,};},},columns: {type: Array,default: () => [],},pageSizes: {type: Array,default: () => [10, 25, 50, 100],},
}); 
const emit =  defineEmits(["current-change"]);
// 获取其他绑定属性
const { attrs } = getCurrentInstance();// 引用
const tableWrap = ref(null);
const tableHeight = ref(50); // 默认高度
let resizeObserver = null;//分页
const page = ref({currentPage: 1,pageSize: 10,
});//函数
const handleChangePage = ({ currentPage, pageSize }) => {page.value.currentPage = currentPage;page.value.pageSize = pageSize;emit("current-change", { currentPage, pageSize});
};// 动态计算表格高度
const initResizeObserver = () => {if (!tableWrap.value) return;//   32是分页高度 10和分页的间隔resizeObserver = new ResizeObserver(() => {tableHeight.value = tableWrap.value.offsetHeight - 32 - 10 || 500;});resizeObserver.observe(tableWrap.value);
};// 生命周期
onMounted(() => initResizeObserver());
onUnmounted(() => resizeObserver?.disconnect());
</script><style scoped lang="scss">
.table-wrap {width: 100%;height: 100%;overflow: auto; /* 根据需求适配 */display: flex;flex-direction: column;gap: 10px;
}
</style>

使用方法：

注意由于表格通过ref="tableWrap"获取的高度，然后ref="tableWrap"设置的高度百分百，所以在使用组件的时候注意组件的外层高度如下方的class="universalTable h100"。

但设置双层表头的时候注意需要把二级表头放在subColumns属性中。

table原生属性可直接加在组件上例如“ :border="true"”的写法，属性方法都可支持

javascript"><template><div class="universalTable h100"><universalTable:border="true":columns="columns":tableInfo="tableInfo"ref="refTable"@current-change="handleCurrentChange"><template #name="{ scope }"><span>{{ scope.row.name }}</span></template></universalTable></div>
</template>
<script setup name="Index">
import { ref, reactive, nextTick } from "vue";
//表头数据
const columns = ref([{type: "selection",},{label: "测试",subColumns: [{prop: "date",label: "Date",width: 100,},],},{prop: "name",label: "Name",width: 120,},{prop: "address",label: "Address",},
]);
//列表数据
const tableInfo = ref({tableData: [{date: "2016-05-03",name: "Tom",address: "No. 189, Grove St, Los Angeles",},{date: "2016-05-02",name: "Tom",address: "No. 189, Grove St, Los Angeles",},{date: "2016-05-04",name: "Tom",address: "No. 189, Grove St, Los Angeles",},{date: "2016-05-01",name: "Tom",address: "No. 189, Grove St, Los Angeles",},],total: 100,
});
//分页数据
const page = ref({currentPage: 1,pageSize: 10,
});
//获取分页数据
const handleCurrentChange = ({ currentPage, pageSize }) => {page.value.currentPage = currentPage;page.value.pageSize = pageSize;
};
</script><style scoped lang="scss">
.universalTable {
}
</style>
