Structure of HTML Tables

<!DOCTYPE html>
<html>
<head>
    <title>HTML Table</title>
    <style>
        table {
            width: 100%;
            border-collapse: collapse;
        }
        
        th, td {
            padding: 8px;
            text-align: left;
            border-bottom: 1px solid #ddd;
        }
        
        th {
            background-color: #f2f2f2;
        }
    </style>
</head>
<body>
    <table id="myTable">
        <tr>
            <th>Header 1</th>
            <th>Header 2</th>
            <th>Header 3</th>
        </tr>
        <tr>
            <td>Data 1</td>
            <td>Data 2</td>
            <td>Data 3</td>
        </tr>
        <tr>
            <td>Data 4</td>
            <td>Data 5</td>
            <td>Data 6</td>
        </tr>
    </table>


</body>
</html>

HTML tables are built using a combination of table-related elements, including the <table>, <tr>, <th>, and <td> tags.

Table element: The <table> element serves as the container for the entire table. It is used to define the beginning and end of the table structure.
Table rows and cells: Rows in HTML tables are defined by the <tr> (table row) element. Each row consists of one or more cells, defined by the <td> (table data) element. Cells can contain text, images, links, or any other HTML elements.
Table headings: Table headings are defined using the <th> (table heading) element. They provide a way to label and categorize the data in the table. By default, table headings are rendered in bold and centered within the cell.
Table data: Table data is defined using the <td> element. It represents the actual data that is displayed within the cells of the table.
