正常表格的每一列是按照数据库中的字段来显示的（有多少个字段就有多少列）
例如数据库中某表有两个字段，姓和名，默认情况下是这样显示的
虽然字段可以分开存储，但更合理的是，姓和名一起显示（姓名）

return '';

return {
tableData: [

{ lastName: "李", firstName: "四" },
{ lastName: "王", firstName: "五" },
]
}
}
})
</script>

解决方法
- 获取每一行的索引
<template slot-scope="scope"> {{scope.$index}} </template> - 将
姓和名放到同一列<el-table-column label="姓名" align="center"> <template slot-scope="scope"> {{tableData[scope.$index].lastName}}{{tableData[scope.$index].firstName}} </template> </el-table-column>
解释
- 标签
:data属性：表格绑定的数据
<el-table-column>标签label属性：每列的标题
prop：属性：该列的值在:data中的key
例如:data=tableData，而prop=lastName，就会逐个取出tableData中的lastName
如果列的值是自定义的，就必须删除prop属性tableData: [ { lastName: "张", firstName: "三" }, { lastName: "李", firstName: "四" }, { lastName: "王", firstName: "五" }, ]
