Question

我是Angular2的新手，我有类似这样的json数据，我需要在表格中进行迭代。每个键值都不同，所以我需要插入每个键值或者某些东西可以做得更聪明。如果我有数百行怎么办？

    [
              {
        "medg01morl": "908,25",
        "medg01morh": "910,25",
        "medg01mitl": "905,00",
        "medg01mith": "907,00",
        "medg01abentl": "888,75",
        "medg01abenth": "890,75",
        "medg01vortagl": "889,50",
        "medg01vortagh": "891,50",
        "medd01morl": "936,25",
        "medd01morh": "938,25",
        "medd01mitl": "933,00",
        "medd01mith": "935,00",
        "medd01abentl": "916,75",
        "medd01abenth": "918,75",
        "medd01vortagl": "914,50",
        "medd01vortagh": "916,50",
              }
            ]

aramed:Array<Object>;

    <table *ngFor="let med of aramed">
