CSS Table Alignment

Welcome to The Coding College! Table alignment is crucial for creating visually appealing layouts that match your website’s overall design. CSS gives you the tools to align tables horizontally, vertically, and within other containers for maximum flexibility.

In this guide, you’ll learn how to align tables using CSS properties like text-align, margin, position, and more.

Horizontal Table Alignment

1. Aligning Tables to the Left

By default, tables are left-aligned in HTML. However, you can explicitly define this with CSS:

table {
    margin-left: 0; /* Aligns the table to the left */
}

2. Aligning Tables to the Center

Use margin and auto to center-align your table:

table {
    margin-left: auto;
    margin-right: auto;
    border: 1px solid black; /* Optional border for visibility */
}

3. Aligning Tables to the Right

To align a table to the right, set margin-left to auto:

table {
    margin-left: auto;
    margin-right: 0;
}

Vertical Table Alignment

Vertical alignment ensures your table is positioned correctly within its container or relative to other elements.

1. Aligning a Table to the Top

Set the parent container’s vertical-align property:

.container {
    display: table-cell;
    vertical-align: top; /* Aligns table to the top */
}

table {
    border: 1px solid black;
}

2. Aligning a Table to the Middle

Center the table vertically within its container:

.container {
    display: table-cell;
    vertical-align: middle; /* Aligns table to the middle */
    height: 500px; /* Set height for the container */
}

3. Aligning a Table to the Bottom

Set the vertical-align property to bottom:

.container {
    display: table-cell;
    vertical-align: bottom; /* Aligns table to the bottom */
    height: 500px;
}

Aligning Table Content

You can align the content inside table cells horizontally or vertically.

1. Horizontal Content Alignment

Use the text-align property to align content inside <td> or <th>:

th, td {
    text-align: left;   /* Align text to the left */
    text-align: center; /* Align text to the center */
    text-align: right;  /* Align text to the right */
}

2. Vertical Content Alignment

Use the vertical-align property to control the vertical alignment of cell content:

th, td {
    vertical-align: top;    /* Align to the top */
    vertical-align: middle; /* Center vertically */
    vertical-align: bottom; /* Align to the bottom */
}

Combining Horizontal and Vertical Alignments

Here’s how you can create a table with fully centered content:

table {
    margin: auto; /* Center-align table */
    border: 1px solid black;
    border-collapse: collapse;
}

th, td {
    text-align: center;      /* Horizontal alignment */
    vertical-align: middle;  /* Vertical alignment */
    padding: 10px;
}

Responsive Table Alignment

1. Center Tables on Small Screens

Use media queries to adjust table alignment on smaller devices:

@media (max-width: 600px) {
    table {
        margin-left: auto;
        margin-right: auto;
        font-size: 14px; /* Reduce font size for readability */
    }
}

2. Make Tables Scrollable

For wide tables on small screens, ensure alignment is maintained while allowing scrolling:

.table-container {
    overflow-x: auto;
    text-align: center; /* Center table in the container */
}

table {
    margin: auto;
    border: 1px solid black;
}

Example: Complete Aligned Table

<div class="container">
    <table class="aligned-table">
        <tr>
            <th>Name</th>
            <th>Age</th>
            <th>Country</th>
        </tr>
        <tr>
            <td>John</td>
            <td>25</td>
            <td>USA</td>
        </tr>
        <tr>
            <td>Maria</td>
            <td>30</td>
            <td>Spain</td>
        </tr>
    </table>
</div>
.container {
    display: flex;
    justify-content: center; /* Center horizontally */
    align-items: center;    /* Center vertically */
    height: 100vh;          /* Full viewport height */
}

.aligned-table {
    width: 80%;
    border-collapse: collapse;
    margin: auto;
}

.aligned-table th, .aligned-table td {
    border: 1px solid #ddd;
    text-align: center;
    padding: 8px;
}

.aligned-table th {
    background-color: #4CAF50;
    color: white;
}

Accessibility Tips

  1. Use Semantic Markup: Always use <table>, <thead>, <tbody>, and <tfoot> for accessibility and search engines.
  2. Avoid Empty Cells: Add placeholders like — to improve readability.
  3. Responsive Alignment: Ensure tables adapt well to different screen sizes without breaking the layout.

Conclusion

CSS alignment techniques give you full control over table positioning, both inside its container and within the content itself. Whether you’re working on data tables or design-focused layouts, proper alignment enhances user experience and readability.
