解决办法：在每个el-table-column添加一个key

<el-table :data="totalRevenuetableData"
            style="width: 100%" ref="one">
            <el-table-column prop="collectTime" :key='Math.random()'
              label="时间">
            </el-table-column>
            <el-table-column :key='Math.random()'
              label="昵称"
              prop="accountName">
            </el-table-column>
            <el-table-column prop="totalAmount" :key='Math.random()'
              label="总收益（元）">
            </el-table-column>
            <el-table-column prop="totalPlatformAmount" :key='Math.random()'
              label="平台补贴（元）">
            </el-table-column>
            <el-table-column prop="totalContentAmount" :key='Math.random()'
              label="内容分成（元）">
            </el-table-column>
          </el-table>
