Table left border too thick, and background colour not filling within border radius-CodePudding

I have a table that isn't being styled as I expect.

The left side border is too thick, and the background colour on the right doesn't quite fit perfectly within the border radius:

I'm not sure why this, any ideas? I've included my code with an MWE.

table {
    font-family: Avenir, Helvetica, Arial, sans-serif;
    width: 100%;
    background-color: #ffffff;
    border-collapse: collapse;
    border-width: 2px;
    border-color: #dedede;
    border-style: solid;
    color: #000000;
    border-radius: 10px;
    border-collapse: separate !important;
    border-spacing: 0;
  }

  table td, table th {
    border-right: solid 1px #dedede;
    border-left: solid 1px #dedede;
    padding: 10px;
  }

  table thead {
    font-size: 1.6em;
  }

  table th:last-child {
    border-right: 0px;
    border-top-right-radius: 10px;
    background-color: #edf2f4;
  }

  table td:last-child {
    border-right: 0px;
    background-color: #edf2f4;
  }

  .last-td {
    border-right: 0px;
    border-bottom-right-radius: 10px;
    background-color: #edf2f4;
  }

<table>
  <thead>
    <tr>
      <th> alpha </th>
      <th> beta </th>
    </tr>
  </thead>
  <tbody>

    <tr>
      <td> lorem </td>
      <td> lorem </td>
    </tr>
  </tbody>
</table>

In my solution, everything looks correct.

table {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  width: 100%;
  background-color: #ffffff;
  border-collapse: separate;
  border-spacing: 0;
}
table tr th,
table tr td {
  border-right: 2px solid #dedede;
  border-bottom: 2px solid #dedede;
  padding: 10px;
}

table tr th:first-child,
table tr td:first-child {
  border-left: 2px solid #dedede;
}
table tr th:first-child,
table tr td:first-child {
  border-left: 2px solid #dedede;
}
table tr th {
  background: #eee;
  text-align: left;
  border-top: solid 2px #dedede;
}

table td:last-child {
  background-color: #edf2f4;
}

/* top-left border-radius */
table tr:first-child th:first-child {
  border-top-left-radius: 10px;
}

/* top-right border-radius */
table tr:first-child th:last-child {
  border-top-right-radius: 10px;
}

/* bottom-left border-radius */
table tr:last-child td:first-child {
  border-bottom-left-radius: 10px;
}

/* bottom-right border-radius */
table tr:last-child td:last-child {
  border-bottom-right-radius: 10px;
}

<div>
    <table>
        <tr>
            <th>item1</th>
            <th>item2</th>
        </tr>
        <tr>
            <td>item1</td>
            <td>item2</td>
        </tr>
        <tr>
            <td>item1</td>
            <td>item2</td>
        </tr>
        <tr>
            <td>item1</td>
            <td>item2</td>
        </tr>
    </table>
</div>

The border at right was thinner than left because of this line - border-right: 0px;. The last <td> and <tr>'s right border had 0 px while the first ones had 1 px on their left which resulted in border being thicker. The below code will solve that problem.

table {
  font-family: Avenir, Helvetica, Arial, sans-serif;
  width: 100%;
  background-color: #ffffff;
  border-collapse: collapse;
  border-width: 2px;
  border-color: #dedede;
  border-style: solid;
  color: #000000;
  border-radius: 10px;
  border-collapse: separate !important;
  border-spacing: 0;
}

table td,
table th {
  border-right: solid 1px #dedede;
  border-left: solid 1px #dedede;
  padding: 10px;
}

table thead {
  font-size: 1.6em;
}

table th:last-child {
  border-top-right-radius: 10px;
  background-color: #edf2f4;
}

table td:last-child {
  background-color: #edf2f4;
}

.last-td {
  border-right: 0px;
  border-bottom-right-radius: 10px;
  background-color: #edf2f4;
}

<table>
  <thead>
    <tr>
      <th> alpha </th>
      <th> beta </th>
    </tr>
  </thead>
  <tbody>

    <tr>
      <td> lorem </td>
      <td> lorem </td>
    </tr>
  </tbody>
</table>

You have used border twice in your code for th and td

table {
    font-family: Avenir, Helvetica, Arial, sans-serif;
    width: 100%;
    background-color: #ffffff;
    border-collapse: collapse;
    border-width: 2px;
    border-color: #dedede;
    border-style: solid;
    color: #000000;
    border-radius: 10px;
    border-collapse: separate !important;
    border-spacing: 0;
  }

  
  table td, table th {
    border-right: solid 1px #dedede;
    padding: 10px;
  }

  table thead {
    font-size: 1.6em;
  }

  table th:last-child {
    border-right: 0px;
    border-top-right-radius: 8px;
    background-color: #edf2f4;
  }

  table td:last-child {
    border-right: 0px;
    border-bottom-right-radius: 8px;
    background-color: #edf2f4;
  }

  .last-td {
    border-right: 0px;
    border-bottom-right-radius: 10px;
    background-color: #edf2f4;
  }
