Answer 1

You can learn about <table> tags at MDN You can do this:

table, th, td {
  border: 1px solid black;
  border-collapse: collapse;
}

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" />

<table class="table table-bordered">
  <thead>
    <tr>
      <th colspan="2">Subject</th>
      <th>Result</th>
    </tr>

  </thead>
  <tbody>
    <tr>
      <td rowspan="2">Science</td>
      <td>Physics</td>
      <td>A</td>

    </tr>
    <tr>
      <td>Chemistry</td>
      <td>A</td>
    </tr>
    <tr>
      <td rowspan="2">Other Science</td>
      <td>Biology</td>
      <td>B</td>
    </tr>
    <tr>
      <td>Geography</td>
      <td>A</td>
    </tr>
    <tr>
      <td colspan="2">Math</td>
      <td>A+</td>
    </tr>
    <tr>
      <td colspan="2">English</td>
