el-table-column行按钮防重控制loading

无需初始化el-table的:data，直接加:loading="scope.row.installBtn"即可！

<el-table-column label="操作">
  <template slot-scope="scope">
    <el-button 
     :loading="scope.row.installBtn" size="mini" 
     @click="handleInstall(scope.row)" type="primary">安装 </el-button> </template> </el-table-column> handleInstall(row){
    
	row.installBtn = true 请求...{
    
		row.installBtn = false
	}
	

如果请求用request.js包裹比较特殊，出错时的row.installBtn = false不生效，则：(el-table的:data=dataList)

<el-table-column label="操作">
  <template slot-scope="scope">
    <el-button 
     :loading="scope.row.installBtn" size="mini" 
     @click="handleInstall(scope.row,scope.$index)" type="primary">安装 </el-button> </template> </el-table-column> handleInstall(row,currentIndex){
    
	this.$set(this.dataList[currentIndex],'installBtn',true) 请求...{
    
		this.$set(this.dataList[currentIndex],'installBtn',false)
	}
