• 代码如下：

    <el-dialog
        :visible.sync="dialogVisible"
        style="padding:0;"
        width="30%">
        <button class="dialogButton" @click="changeStatus(20010)">未开发</button>
        <button class="dialogButton" @click="changeStatus(20011)">进行中</button>
        <button class="dialogButton" @click="changeStatus(20012)">测试中</button>
        <button class="dialogButton" @click="changeStatus(20013)">待发布</button>
        <button class="dialogButton" @click="changeStatus(20014)">已完成</button>
    </el-dialog>

 <el-table

  // 单击表格

• 样式文件：

   .el-table tr td.developing{
      background: #FFE4B5;
      opacity:0.9;
    }
    .el-table tr td.testing{
      background: #FFA500;
      opacity:0.9;
    }
    .el-table tr td.publishing{
      background: #87CEFA;
      opacity:0.9;
    }
    .el-table tr td.published{
      background: #9ACD32;
      opacity:0.9;
    }
