Answer 1

The problem is, that you need to make the certain inner elements round.

So you have to make for the first th and the last th round to get the wished solution.

table th:first-child{
  border-radius:10px 0 0 10px;
}

table th:last-child{
  border-radius:0 10px 10px 0;
}

Answer 2

There are a number of options. It depends on what you really want to achieve visually.

But be sure that border-collapse is NOT set to collapse, because that will not work. For more information, see this mozilla link: https://developer.mozilla.org/en/CSS/border-radius

#uno,
#due th,
#tre th {
  border-top-right-radius: 10px;
  border-top-left-radius: 10px;
  border: 1px solid black;
}
#tre td {
  border: 1px solid black;
}

<table id="uno" border="0">
  <tr>
    <th>Header 1</th>
    <th>Header 2</th>
  </tr>
  <tr>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
  </tr>
  <tr>
    <td>row 2, cell 1</td>
    <td>row 2, cell 2</td>
  </tr>
</table>

<table id="due" border="1">
  <tr>
    <th>Header 1</th>
    <th>Header 2</th>
  </tr>
  <tr>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
  </tr>
  <tr>
    <td>row 2, cell 1</td>
    <td>row 2, cell 2</td>
  </tr>
</table>

<table id="tre" border="0">
  <tr>
    <th>Header 1</th>
    <th>Header 2</th>
  </tr>
  <tr>
    <td>row 1, cell 1</td>
    <td>row 1, cell 2</td>
  </tr>
  <tr>
    <td>row 2, cell 1</td>
    <td>row 2, cell 2</td>
  </tr>
</table>
