element official data is a string. I judge whether the data is passed or not according to the status of 0, 1 and 2. Please tell me how to filter this
   
    <el-table-column prop="iwaAuditStatus" column-key="status" label="" :filters="[{ text: "", value: "" }, { text: "", value: "" },{ text: "", value: "" }]" :filter-method="filterTag" filter-placement="bottom-end">
                <template slot-scope="scope">
                    <el-tag type="success" v-if="scope.row.iwaAuditStatus == 1"></el-tag>
                    <el-tag  v-else-if="scope.row.iwaAuditStatus == 0"></el-tag>
                    <el-tag type="danger" v-else-if="scope.row.iwaAuditStatus == 2"></el-tag>
                </template>
    </el-table-column>
