    <h2>8. HTML Tables</h2>

    <h3>I. Basic Table Structure</h3>
    <p><strong>Explanation:</strong> Table banane ke liye <code>&lt;table&gt;</code> tag ka use hota hai. Row ke liye <code>&lt;tr&gt;</code>, column ke liye <code>&lt;td&gt;</code> aur heading ke liye <code>&lt;th&gt;</code> use hota hai.</p>

    <textarea id="code1">
<table border="1">
  <tr>
    <th>Name</th>
    <th>Age</th>
  </tr>
  <tr>
    <td>Rahul</td>
    <td>22</td>
  </tr>
  <tr>
    <td>Aisha</td>
    <td>24</td>
  </tr>
</table>
    </textarea>
    <button onclick="runCode('code1', 'output1')">Run Code</button>
    <iframe id="output1"></iframe>

    <h3>II. Table Borders and Padding</h3>
    <p><strong>Explanation:</strong> Table mein border aur spacing control karne ke liye CSS ya <code>cellpadding</code> use karte hain.</p>

    <textarea id="code2">
<table border="1" cellpadding="10">
  <tr>
    <th>Product</th>
    <th>Price</th>
  </tr>
  <tr>
    <td>Laptop</td>
    <td>$999</td>
  </tr>
  <tr>
    <td>Mouse</td>
    <td>$25</td>
  </tr>
</table>
    </textarea>
    <button onclick="runCode('code2', 'output2')">Run Code</button>
    <iframe id="output2"></iframe>

    <h3>III. Merging Cells (colspan & rowspan)</h3>
    <p><strong>Explanation:</strong> Kisi cell ko horizontally ya vertically merge karne ke liye <code>colspan</code> (columns) aur <code>rowspan</code> (rows) ka use hota hai.</p>

    <textarea id="code3">
<table border="1" cellpadding="8">
  <tr>
    <th colspan="2">Student Info</th>
  </tr>
  <tr>
    <td>Name</td>
    <td>Meena</td>
  </tr>
  <tr>
    <td rowspan="2">Subjects</td>
    <td>Math</td>
  </tr>
  <tr>
    <td>Science</td>
  </tr>
</table>
    </textarea>
    <button onclick="runCode('code3', 'output3')">Run Code</button>
    <iframe id="output3"></iframe>

  </div>

  <script>
    function runCode(textareaId, iframeId) {
      const code = document.getElementById(textareaId).value;
      const iframe = document.getElementById(iframeId);
      const doc = iframe.contentDocument || iframe.contentWindow.document;
      doc.open();
      doc.write(code);
      doc.close();
    }
  </script>
</body>
