前端：

加入按钮 抽屉  抽屉内直接写内容样式  调用值

       <el-button
            size="mini"
            type="text"
            icon="el-icon-view"
            @click="showDrawer(scope.row)"
            v-hasPermi="['enforceLaw:caseParamsLog:list']"
          >查看历史记录</el-button>
          <el-drawer
            :visible.sync="drawerVisible"
            :direction="drawerDirection"
            :before-close="handleClose"
            append-to-body
          >
            <div slot="title" v-for="(log, index) in logList" :key="index">
              <h4 v-if="index === 0">{{ log.paramsKey }}<dict-tag :options="dict.type.case_params_key" :value="logList[0].paramsKey"/></h4>

            </div>
            <div class="log-item" v-for="(log, index) in sortedLogList" :key="index">
              <el-timeline>
                <el-timeline-item placement="top">
                  <el-card>
                    <p>创建人：{{ log.createBy }} 创建于 {{ log.createTime }}</p>
                    <p>变更位置：{{ log.changeLocation }}</p>
                    <p>旧值：{{ log.oldParamsValue }}</p>
                    <p>新值：{{ log.newParamsValue }}</p>
                  </el-card>
                </el-timeline-item>
              </el-timeline>
            </div>
          </el-drawer>

需要的方法/数据

    showDrawer(row) {
      const caseId = row.caseId;
      const paramsKey = row.paramsKey;
      listCaseParamsLog({caseId:caseId,paramsKey:paramsKey}).then(response => {
        this.logList = response.rows;
        this.loading = false;
        this.drawerContent = this.logList; // 将日志列表赋值给drawerContent
        this.drawerVisible = true; // 打开抽屉
      });
    },




 data() {
    return {
      drawerVisible: false,
      drawerDirection: "ltr",
      drawerTitle: "", // variable to store the drawer title
      // 遮罩层
      loading: true,
      //可选项列表
      dataList: [],
      logList: [],




  computed: {
    row() {
      return row
    },
    sortedLogList() {
      return this.logList.sort((a, b) => new Date(b.createTime).getTime() - new Date(a.createTime).getTime());
    }
  },
