element-ui 封装 表格

一、封装表格组件

<template>
  <el-table :data="list" :default-sort="{ prop: 'date' }" style="width: 100%">
    <template v-for="item in tableColumn">
      <el-table-column
        v-if="item.filters"
        :prop="item.prop"
        :label="item.label"
        :sortable="item.sortable"
        :filters="item.filters"
        :filter-method="filterHandler(item.filterMethod)"
      />
      <el-table-column
        v-if="!item.filters"
        :prop="item.prop"
        :label="item.label"
        :sortable="item.sortable"
      />
    </template>
  </el-table>
</template>

<script scoped>
export default {
  data() {
    return {
      list: [],
      tableColumn: [],
    };
  },
  props: {
    data: {
      type: Array,
      default: [],
    },
    column: {
      type: Array,
      default: [],
    },
  },
  watch: {
    data: {
      immediate: true,
      deep: true,
      handler(val) {
        if (val.length) {
          this.list = JSON.parse(JSON.stringify(val));
        }
      },
    },
    column: {
      immediate: true,
      deep: true,
      handler(val) {
        if (val.length) {
          this.tableColumn = JSON.parse(JSON.stringify(val));
        }
      },
    },
  },
  methods: {
    // 如果没传，那么默认等值判断
    filterHandler(filterMethod) {
      if (filterMethod) {
        return item.filterMethod;
      } else {
        return (value, row, column) => {
          const property = column["property"];
          return row[property] === value;
        };
      }
    },
  },
};
</script>

二、使用方法

<template>
  <div id="app"><Tabel :data="data" :column="column" /></div>
</template>

<script>
import Tabel from "@/components/Tabel.vue";
export default {
  components: { Tabel },
  data() {
    return {
      column: [
        {
          label: "日期",
          prop: "date",
          sortable: true,
        },
        {
          label: "姓名",
          prop: "name",
          filters: [{ text: "王小龙", value: "王小龙" }],
        },
        {
          label: "地址",
          prop: "address",
        },
      ],
      data: [
        {
          date: "2016-05-02",
          name: "王小猪",
          address: "上海市普陀区金沙江路 1518 弄",
        },
        {
          date: "2016-05-04",
          name: "王小虎",
          address: "上海市普陀区金沙江路 1517 弄",
        },
        {
          date: "2016-05-01",
          name: "王小龙",
          address: "上海市普陀区金沙江路 1519 弄",
        },
        {
          date: "2016-05-03",
          name: "王小海",
          address: "上海市普陀区金沙江路 1516 弄",
        },
      ],
    };
  },
};
</script>
