数据形式

task = [
      { 
        name: "test1",
        group: { 
          1: { 
            phase: { 
              "Start": { 
                status: "Wait",
                complete_time: "2021-04-12 12:12:12",
                msg: "",
              },
              "Finish": { 
                status: "Wait",
                complete_time: "2021-04-12 12:12:12",
                msg: "",
              },
            },
          },
          2: { 
            phase: { 
              "Start": { 
                status: "Wait",
                complete_time: "2021-04-12 12:12:12",
                msg: "",
              },
              "Finish": { 
                status: "Wait",
                complete_time: "2021-04-12 12:12:12",
                msg: "",
              },
            },
          },
        },
      },
    ];

其中1，2是value，无key，需要将group转换为含key值的数组，使用`Object.entries(item)`方法

getTable()  { 
      var table: any = [];
      for (let i = 0; i < task.length; i++) { 
        var tableData: any = [];
        var item = task[i].group;
        for (const [key, value] of Object.entries(item)) { 
          console.log(key, value);
          tableData.push({ 
            device_id: key,
            start_time: value["phase"]["Start"]["complete_time"],
            end_time: value["phase"]["Finish"]["complete_time"],
          });
        }
        table.push(tableData);
        return table;
      }
    }

转换之后

table = [
    	{ 
    	device_id: "1"
    	end_time: "2021-04-12 12:12:12"
    	start_time: "2021-04-12 12:12:12"
    	},
    	{ 
    	device_id: "2"
    	end_time: "2021-04-12 12:12:12"
    	start_time: "2021-04-12 12:12:12"
    	}
    ]
