这里标题&我的component.ts中的catNames var：

catNames : string[] = ["Toto","Tata","Titi","Mama","Momo"];
headers: string[] = ["Head1","Head2","Head3","Head4","Head5"];

这是我的组件HTML：

<table>
  <tr>
    <th *ngFor="let header of headers">
        {{header}}
    </th>
  </tr>
  <tr>
    <td *ngFor="let cat of catNames">
        <p>{{cat}}</p>
    </td>
  </tr>
</table>

这是我的CSS：

table {
    font-family: 'Gill Sans','Gill Sans MT',Calibri,'Trebuchet MS',sans-serif;
    border-collapse: collapse;
    text-align: center;
    width: 100%;
    font-size: 12pt;
}

th {
    border: 1px solid #dddddd;
    text-align: center;
    padding: 0px;
    color: white;
    background-color: dodgerblue;
}

td {
    display:table-cell;
    border: 1px solid #dddddd;
    text-align:  center;
    margin: 0;
    padding: 0;
    border-spacing: 0;
}

如何显示,我想删除顶部和顶部的额外空间细胞的下边界：

我的CSS值有错吗？
