📊 CSS Tables – Styling HTML Tables for Better Design & Accessibility

HTML tables are essential for displaying structured data like pricing lists, schedules, and reports. However, without proper styling, they can appear dull and hard to read. With CSS table styling, you can transform basic tables into visually appealing and accessible data components that work well across all devices.

This guide covers everything from borders and alignment to responsiveness and accessibility—with output examples to show how each style works.

🔰 Introduction – Why CSS Table Styling Matters

Imagine comparing pricing plans in a poorly formatted table: misaligned columns, inconsistent spacing, and zero visual hierarchy. Poor presentation leads to confusion.

That’s why CSS table styling is crucial—it enhances readability, responsiveness, and overall user experience.

By the end, you’ll be able to:

• Add visual clarity to your tables
• Style headers, borders, and cells
• Make tables responsive for mobile devices
• Improve accessibility using semantic tags

🧱 Default HTML Table Structure

Here’s a plain HTML table:

<table>
  <thead>
    <tr>
      <th>Item</th>
      <th>Price</th>
      <th>Quantity</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Apples</td>
      <td>$2</td>
      <td>10</td>
    </tr>
    <tr>
      <td>Oranges</td>
      <td>$3</td>
      <td>5</td>
    </tr>
  </tbody>
</table>

🔽 Output:

Item	Price	Quantity
Apples	$2	10
Oranges	$3	5

👉 Basic but unstyled and not user-friendly.

🎨 CSS Table Styling Basics

🧩 Adding Borders and Spacing

table {
  border-collapse: collapse;
  width: 100%;
}

th, td {
  border: 1px solid #ccc;
  padding: 12px;
  text-align: left;
}

🔍 Explanation:

• border-collapse: collapse merges adjacent borders.
• padding and border give cells breathing room.
• width: 100% makes the table span its container.

🔽 Styled Output:

Item	Price	Quantity
Apples	$2	10
Oranges	$3	5

Now with clear cell boundaries and readable spacing.

🪄 Zebra Striping Rows

tbody tr:nth-child(odd) {
  background-color: #f9f9f9;
}

🎯 Why use this? Alternating row colors help distinguish rows in large datasets.

🔽 Striped Output:

Item	Price	Quantity
Apples	$2	10
Oranges	$3	5

✨ Alternating background improves scanning.

---

🧭 Styling Table Headers

thead {
  background-color: #333;
  color: white;
  font-weight: bold;
}

✔️ Result: A bold, high-contrast header.

🔽 Header Styled Output:

Item	Price	Quantity
Apples	$2	10
Oranges	$3	5

🖤 Headers now visually separated from data.

📱 Making Tables Responsive

.table-container {
  overflow-x: auto;
}

table {
  width: 100%;
  min-width: 600px;
}

🧪 HTML Usage:

<div class="table-container">
  <table>...</table>
</div>

📱 On mobile:

• The table scrolls horizontally
• Prevents overflow without collapsing layout

🔽 Responsive Behavior:

• Table stays full-width on desktop.
• Scroll bar appears on small screens.

---

🎛️ Controlling Column Widths and Alignment

td:nth-child(2) {
  text-align: right;
  width: 120px;
}

📏 Use case: Align numeric values or currency.

🔽 Aligned Output:

Item	Price	Quantity
Apples	$2	10
Oranges	$3	5

Numbers are now right-aligned and easier to compare.
