1.关于图片+文字的封装

<el-col
            :span="8"
            v-for="(item, index) in main_title"
            :key="index"
            class="main_title"
          >
            <img :src="require('../assets/image/icon/' + item.img + '.png')" class="img" />
            <div>
              <p class="title1">{{ item.text }}</p>
              <p class="text1">{{ item.title }}</p>
            </div>
          </el-col>
main_title: [
        {
        img: "icon1",
        title: "资产总数",
        text: "45个"
      },
   
      ],

2.select选择器的封装

<el-select v-model="form.plan" placeholder="请选择" style="width: 100%" @change="bclxChange">
          <el-option
            v-for="item in plan_options"
            :key="item.value"
            :label="item.label"
            :value="item.value"
          >
          </el-option>
        </el-select>
plan_options: [
        {
          value: "1",
          label: "一次性任务",
        },
        {
          value: "2",
          label: "计划性任务",
        },
      ],
//选择不同项显示不同内容
bclxChange(selectValue) {
      if (selectValue == 1) {
        this.show = true;
        this.hidden= false;
      }
      if (selectValue == 2) {
        this.show = false;
        this.hidden=true;
      }
    },

3.关于按钮展开或显示内容的封装

<el-from id="searchBox"></el-from>
<el-button
            type="text"
            style="margin-left: 10px"
            id="closeSearchBtn"
            @click="closeSearch"
          >
            {{ word }}
            <i
              :class="showAll ? 'el-icon-arrow-up ' : 'el-icon-arrow-down'"
            ></i>
          </el-button>
export default {
  data() {
    return {
       showAll:true,
       }
      },
 computed: {
    word: function() {
   if (this.showAll == false) {
    //对文字进行处理
    return "展开搜索";
   } else {
    return "收起搜索";
   }
  }
  },
  mounted() {
    this.$nextTick(function() {
   this.closeSearch();
  });
  },
   methods: {
    closeSearch() {
   this.showAll = !this.showAll;
   var searchBoxHeght = document.getElementById("searchBox");
   if (this.showAll == false) {
    searchBoxHeght.style.height = 60 + "px";
   } else {
    searchBoxHeght.style.height = "auto";
   }
  }
  },
  }

注意这个一定要加


#searchBox {
 overflow: auto;
}

4.表格中加入进度条

<el-table-column property="rate" label="使用率">
        <template #default="scope">
          <el-progress
            type="line"
            :text-inside="true"
            :percentage="scope.row.progress"
            :color="scope.row.color"
            :stroke-width="24"
          ></el-progress>
        </template>
      </el-table-column>
tableData: [
        {
                progress: 50,
                color: "red",
              },
      ],

5.element-plus表单中input框和select框等宽等长

//直接在el-select中加入style="width: 100%"
 <el-select  style="width: 100%" > </el-select>

6.表格中的序号按照顺序排列

<el-table-column type="index" label="序号" width="50" :index="indexMethod"> </el-table-column>
methods: {
indexMethod(index) {
      return index + 1 + (this.currentPage - 1) * this.pageSize;
    },
    }

7.表格中加入开关控制按钮

<el-table-column label="生效配置">
            <template #default="scope">
              <el-switch
                v-model="scope.row.status"
                active-color="#13ce66"
                inactive-color="#ff4949"
              />
            </template>
          </el-table-column>
tableData: [
        {
          status: true,
        },
      ],
