Data Table Role in Dashboards
Data tables are one of the most common components in admin dashboards. They display structured records — users, orders, transactions — in rows and columns, often with sorting, filtering, and pagination controls. A well-styled Tailwind table is readable, scannable, and interactive. The table is typically placed below the stat cards in the main content area.
Table Container and Wrapper
Wrap the table in a rounded-xl bg-white shadow-sm overflow-hidden card container. The overflow-hidden clips the table corners to match the card's border radius. Inside the card, add a table header with the table title and action buttons, followed by an overflow-x-auto div that allows horizontal scrolling on mobile without breaking the layout.
<div class="rounded-xl bg-white shadow-sm overflow-hidden">
<!-- Table header bar -->
<div class="flex items-center justify-between border-b border-gray-100 px-6 py-4">
<h3 class="font-semibold text-gray-900">Recent Users</h3>
<button class="text-sm font-medium text-blue-600 hover:text-blue-700">View all</button>
</div>
<!-- Scrollable table -->
<div class="overflow-x-auto">
<table class="w-full text-sm">
<!-- thead and tbody -->
</table>
</div>
</div>Table Header Row
The thead contains column labels. Use bg-gray-50 for the header row background to visually distinguish it from data rows. Each th gets px-6 py-3 text-left text-xs font-semibold uppercase tracking-wider text-gray-500 — a classic small-caps header style that is compact and professional.
<thead class="bg-gray-50">
<tr>
<th scope="col"
class="px-6 py-3 text-left text-xs font-semibold uppercase tracking-wider text-gray-500">
Name
</th>
<th scope="col"
class="px-6 py-3 text-left text-xs font-semibold uppercase tracking-wider text-gray-500">
Email
</th>
<th scope="col"
class="px-6 py-3 text-left text-xs font-semibold uppercase tracking-wider text-gray-500">
Status
</th>
<th scope="col"
class="px-6 py-3 text-left text-xs font-semibold uppercase tracking-wider text-gray-500">
Role
</th>
<th scope="col" class="relative px-6 py-3"><span class="sr-only">Actions</span></th>
</tr>
</thead>Striped Table Rows
Alternating row colors (striped rows) improve readability in dense tables by making it easy to track a row across columns. In Tailwind, use the even:bg-gray-50 variant on tr elements to color even rows and leave odd rows white. Add hover:bg-blue-50 transition-colors for a hover highlight that helps users identify the row under their cursor.
<tbody class="divide-y divide-gray-100 bg-white">
<tr class="even:bg-gray-50 hover:bg-blue-50 transition-colors">
<td class="whitespace-nowrap px-6 py-4">
<div class="flex items-center gap-3">
<img src="/avatar.jpg" class="h-8 w-8 rounded-full" alt="">
<div>
<p class="font-medium text-gray-900">Alice Johnson</p>
<p class="text-xs text-gray-500">Joined Jan 2026</p>
</div>
</div>
</td>
<td class="whitespace-nowrap px-6 py-4 text-gray-500">alice@example.com</td>
<!-- More cells -->
</tr>
</tbody>Status Badge in Table Cells
Status columns use small colored badges to communicate state at a glance. Define three or four status variants: Active (green), Inactive (gray), Pending (yellow), Suspended (red). Each badge uses inline-flex items-center rounded-full px-2.5 py-0.5 text-xs font-semibold with color-appropriate background and text classes applied conditionally based on the status value.
<td class="whitespace-nowrap px-6 py-4">
<!-- Active -->
<span class="inline-flex items-center rounded-full bg-green-100 px-2.5 py-0.5
text-xs font-semibold text-green-800">
Active
</span>
<!-- Pending -->
<span class="inline-flex items-center rounded-full bg-yellow-100 px-2.5 py-0.5
text-xs font-semibold text-yellow-800">
Pending
</span>
<!-- Suspended -->
<span class="inline-flex items-center rounded-full bg-red-100 px-2.5 py-0.5
text-xs font-semibold text-red-800">
Suspended
</span>
</td>Table Action Buttons
The last column of each row contains row-level actions: Edit, Delete, or View. Align these with text-right on the th and td. Use text-only buttons styled as links to keep the table clean: text-sm font-medium text-blue-600 hover:text-blue-700 for Edit and text-red-500 hover:text-red-700 for Delete. Separate them with a light divider: mx-3 text-gray-300.
<td class="whitespace-nowrap px-6 py-4 text-right">
<a href="/users/1/edit"
class="text-sm font-medium text-blue-600 hover:text-blue-700">
Edit
</a>
<span class="mx-2 text-gray-300">|</span>
<button onclick="deleteUser(1)"
class="text-sm font-medium text-red-500 hover:text-red-700">
Delete
</button>
</td>Pagination Controls
Pagination controls sit below the table. A common pattern shows Showing 1 to 10 of 48 results on the left and Previous/Next buttons on the right. Use flex items-center justify-between border-t border-gray-100 px-6 py-4 for the pagination bar container, keeping it visually attached to the table above it.
<div class="flex items-center justify-between border-t border-gray-100 px-6 py-4">
<p class="text-sm text-gray-500">
Showing <span class="font-medium">1</span> to <span class="font-medium">10</span>
of <span class="font-medium">48</span> results
</p>
<div class="flex gap-2">
<button class="rounded-lg border border-gray-300 px-3 py-1.5 text-sm
font-medium text-gray-700 transition hover:bg-gray-50
disabled:cursor-not-allowed disabled:opacity-40"
disabled>
Previous
</button>
<button class="rounded-lg border border-gray-300 px-3 py-1.5 text-sm
font-medium text-gray-700 transition hover:bg-gray-50">
Next
</button>
</div>
</div>Chart Placeholder Container
Chart placeholder widgets provide the correct layout and skeleton structure for where a chart library (like Chart.js or Recharts) will render. The placeholder card has a header with the chart title and time period selector, a large content area with fixed height for the chart canvas, and optional legend items below. Using placeholders ensures the dashboard layout is stable before chart data loads.
<div class="rounded-xl bg-white shadow-sm">
<!-- Chart header -->
<div class="flex items-center justify-between border-b border-gray-100 px-6 py-4">
<h3 class="font-semibold text-gray-900">Revenue Over Time</h3>
<select class="rounded-lg border border-gray-200 px-3 py-1.5 text-sm text-gray-600">
<option>Last 7 days</option>
<option>Last 30 days</option>
<option>Last 90 days</option>
</select>
</div>
<!-- Chart canvas area -->
<div class="h-64 p-6">
<!-- Chart.js or Recharts renders here -->
<canvas id="revenue-chart"></canvas>
</div>
</div>Skeleton Chart Placeholder
Before chart data loads, show a skeleton placeholder that mimics the chart's shape. For a bar chart placeholder, use a flex row of bars with animate-pulse. For a line chart, a simple rectangle with rounded corners and animate-pulse works. This prevents the jarring appearance of an empty white box before the chart library initializes.
<!-- Bar chart skeleton -->
<div class="flex h-52 items-end gap-2 animate-pulse">
<div class="flex-1 rounded-t bg-gray-200" style="height: 60%"></div>
<div class="flex-1 rounded-t bg-gray-200" style="height: 80%"></div>
<div class="flex-1 rounded-t bg-gray-200" style="height: 45%"></div>
<div class="flex-1 rounded-t bg-gray-200" style="height: 90%"></div>
<div class="flex-1 rounded-t bg-gray-200" style="height: 70%"></div>
<div class="flex-1 rounded-t bg-gray-200" style="height: 55%"></div>
<div class="flex-1 rounded-t bg-gray-200" style="height: 75%"></div>
</div>Side-by-Side Chart and Table Layout
A common dashboard grid places a chart widget and a table (or secondary stat) side by side. Use a two-column grid: grid grid-cols-1 gap-6 lg:grid-cols-2. The chart and table fill equal columns. You can also use lg:col-span-2 to let one widget span the full width while smaller widgets occupy a third column in a 3-column sub-grid.
<!-- Main dashboard grid: chart + top-users table -->
<div class="mt-6 grid grid-cols-1 gap-6 lg:grid-cols-3">
<!-- Line chart (2/3 width) -->
<div class="rounded-xl bg-white shadow-sm lg:col-span-2">
<!-- Chart content -->
</div>
<!-- Top users list (1/3 width) -->
<div class="rounded-xl bg-white shadow-sm">
<!-- Mini leaderboard -->
</div>
</div>Empty State for Tables
When a table has no data — perhaps filtered to zero results or on a fresh account — show a centered empty state inside the table body. Use a flex column with an icon, a heading, a description, and a CTA button. Avoid showing an empty white box with no context, which disorients users who do not know if the page is broken or simply empty.
<!-- Empty state inside a table or list container -->
<div class="flex flex-col items-center justify-center py-16 text-center">
<svg class="h-12 w-12 text-gray-300" fill="none" stroke="currentColor" viewBox="0 0 24 24">
<path stroke-linecap="round" stroke-linejoin="round" stroke-width="1.5"
d="M20 13V6a2 2 0 00-2-2H6a2 2 0 00-2 2v7m16 0v5a2 2 0 01-2 2H6a2 2 0 01-2-2v-5m16 0H4"/>
