前端配合elementui中table进行筛选

<el-input
              v-model="allSubscribed"
              placeholder="数据项名称"
              suffix-icon="el-icon-search"
            ></el-input>
            //输入框中的东西就是需要筛选的东西
            <div class="tableList">
            //.filter(item=>item.dataName.includes(allSubscribed))，dataName是我要对应的数据
              <el-table
                :data="tableData.stayData.filter(item=>item.dataName.includes(allSubscribed))"
                style="
                  width: 100%;
                  border-radius: 5px;
                  background: rgba(250, 250, 250, 1);
                "
              >
                <el-table-column
                  type="index"
                  label="序号"
                  width="80"
                  align="center"
                >
                </el-table-column>
                <el-table-column prop="cdataId" label="数据项ID" align="center">
                </el-table-column>
                <el-table-column
                  prop="dataName"
                  label="数据项名称"
                  align="center"
                >
                </el-table-column>
