封装此公共组件通过具名插槽的方式来达到自定义table的效果

模板的html的写法：

    <div>
        <el-table
                :cell-style="{'text-align':'center'}"
                :data="tableData"
                border
                :header-cell-style="headerCellStyle"
                style="width: 100%"
                v-loading="loading">
            <template v-for="(col,index) in fieldList">
                <!--是否出现多选框的列-->
                <slot v-if="col.slot" :name="col.slot">
                </slot>
                <!--普通列-->
                <el-table-column v-else :key="index" :prop="col.prop" :label="col.label" :width="col.width"
                                 align="center">
                </el-table-column>
            </template>
        </el-table>
        <!-- 是否调用分页 -->
        <el-pagination v-if="pageObj"
                       layout="total, prev, pager, next, jumper"
                       :page-size="pageObj.size"
                       :total="pageObj.total"
                       :current-page="pageObj.currentPage"
                       @current-change="handlerPage()">
        </el-pagination>

    </div>

js的写法：

<script>
    export default {
        name: "commonTable",
        props:{
            //显示数据
            tableData:Array,
            //设置整个table表格的宽度
            width:String,
            //
            fieldList:Array,
            //设置多级表头的list
            setMultiLevelHeaderList:Array,
            loading:Boolean,
            //是否加上分页
            pageObj:Object,
            headerCellStyle:headerCellStyle
        },
        methods:{
            handlerPage(val){
                this.$emit('handlerPage',val);
            }
        }
    }
</script>

如何使用html的写法:

<!--使用封装之后的公共表格-->
<common-table :tableData="classroomTableData"  @handlerPage="handlerPage" :headerCellStyle="headerCellStyle" :loading="loading" :pageObj="pageObj" width="100%" :fieldList="fieldList">
    <el-table-column slot="多选" type="selection" width="55">
    </el-table-column>
    <el-table-column
            label="操作"
            slot="操作"
    >
        <template slot-scope="scope">
            <el-button type="text">详情</el-button>
            <el-button type="text">修改名称</el-button>
        </template>
    </el-table-column>
    <el-table-column
            prop="studentAddClassroomSetting"
            label="学生加班设置"
            slot="下拉选框"
    >
        <template slot-scope="scope">
            <el-select size="small" v-model="classroomValue" @change="selectClassType"   placeholder="请选择" >
                <el-option
                        v-for="item in classroomList"
                        :key="item.value"
                        :label="item.label"
                        :value="item.value">
                </el-option>
            </el-select>

        </template>
    </el-table-column>
    <el-table-column
            prop="studentChangeName"
            label="允许学生改名"
            slot="switch"
    >
        <template slot-scope="scope">
            <el-switch
                    v-model="nameChangeAllowed"
                    active-text="开"
                    inactive-text="关">
            </el-switch>
        </template>
    </el-table-column>

</common-table>
