Overview

Seizen Table is styled using CSS Variables, making it easy to customize the appearance without writing complex CSS or using CSS-in-JS libraries. All CSS variables have sensible defaults that work out of the box.

​
Quick Start

Define CSS variables in your stylesheet to customize the table: 
:root {
  --szui-color-text: #1f2937;
  --szui-color-bg: #ffffff;
  --szui-border-color: #e5e7eb;
}

​
Color Variables

​
Text and Background

:root {
  /* Primary text color */
  --szui-color-text: #1f2937;
  
  /* Table background color */
  --szui-color-bg: #ffffff;
  
  /* Header background color */
  --szui-header-bg: #f9fafb;
  
  /* Header text color */
  --szui-header-color: #6b7280;
}

​
Interactive States

:root {
  /* Row hover background */
  --szui-row-hover-bg: #f3f4f6;
  
  /* Selected row background */
  --szui-row-selected-bg: #eff6ff;
}

​
Borders

:root {
  /* Border color */
  --szui-border-color: #e5e7eb;
  
  /* Border width */
  --szui-border-width: 1px;
  
  /* Border radius for table container */
  --szui-border-radius: 8px;
}

​
Typography Variables

:root {
  /* Font family */
  --szui-font-family: system-ui, -apple-system, sans-serif;
  
  /* Base font size */
  --szui-font-size: 14px;
  
  /* Line height */
  --szui-line-height: 1.5;
  
  /* Header font size */
  --szui-header-font-size: 12px;
  
  /* Header font weight */
  --szui-header-font-weight: 600;
}

​
Spacing Variables

:root {
  /* Cell horizontal padding */
  --szui-cell-padding-x: 12px;
  
  /* Cell vertical padding */
  --szui-cell-padding-y: 10px;
}

Complete Variable List

Here’s a complete list of all available CSS variables with their defaults: 
:root {
  /* Colors */
  --szui-color-text: #1f2937;
  --szui-color-bg: #ffffff;
  --szui-header-bg: #f9fafb;
  --szui-header-color: #6b7280;
  --szui-border-color: #e5e7eb;
  --szui-row-hover-bg: #f3f4f6;

  --szui-font-family: system-ui, -apple-system, sans-serif;
  --szui-font-size: 14px;
  --szui-line-height: 1.5;
  --szui-header-font-size: 12px;
  --szui-header-font-weight: 600;

  /* Spacing */
  --szui-cell-padding-x: 12px;
  --szui-cell-padding-y: 10px;

  /* Border */
  --szui-border-width: 1px;
  --szui-border-radius: 8px;
}

​
Dark Mode

Implement dark mode using media queries or class-based theming:

​
Media Query Approach

@media (prefers-color-scheme: dark) {
  :root {
    --szui-color-text: #f9fafb;
    --szui-color-bg: #111827;
    --szui-header-bg: #1f2937;
    --szui-header-color: #9ca3af;
    --szui-border-color: #374151;
    --szui-row-hover-bg: #374151;
    --szui-row-selected-bg: #1e3a5f;
  }
}

​
Class-based Approach

/* Light mode (default) */
:root {
  --szui-color-text: #1f2937;
  --szui-color-bg: #ffffff;
  --szui-header-bg: #f9fafb;
  --szui-header-color: #6b7280;
  --szui-border-color: #e5e7eb;
  --szui-row-hover-bg: #f3f4f6;
  --szui-row-selected-bg: #eff6ff;
}

/* Dark mode */
.dark {
  --szui-color-text: #f9fafb;
  --szui-color-bg: #111827;
  --szui-header-bg: #1f2937;
  --szui-header-color: #9ca3af;
  --szui-border-color: #374151;
  --szui-row-hover-bg: #374151;
  --szui-row-selected-bg: #1e3a5f;
}

function App() {
  const [isDark, setIsDark] = useState(false);

  return (
    <div className={isDark ? 'dark' : ''}>
      <SeizenTable table={table} />
    </div>
  );
}

​
Scoped Theming

Apply different themes to different tables on the same page: 
.table-compact {
  --szui-cell-padding-x: 8px;
  --szui-cell-padding-y: 6px;
  --szui-font-size: 12px;
}

.table-spacious {
  --szui-cell-padding-x: 16px;
  --szui-cell-padding-y: 12px;
  --szui-font-size: 16px;
}

<SeizenTable table={compactTable} className="table-compact" />
<SeizenTable table={spaciousTable} className="table-spacious" />

​
Brand Theming Examples

​

:root {
  --szui-color-text: #1e293b;
  --szui-color-bg: #ffffff;
  --szui-header-bg: #f1f5f9;
  --szui-header-color: #475569;
  --szui-border-color: #cbd5e1;
  --szui-row-hover-bg: #f8fafc;

  --szui-header-color: #000000;
  --szui-border-color: #000000;
  --szui-border-width: 2px;
  --szui-row-hover-bg: #e0e0e0;
  --szui-row-selected-bg: #ffeb3b;
}

​
Custom Styling Beyond Variables

For advanced customization beyond CSS variables, you can:
  1. Add custom CSS classes using the className prop
  2. Use custom cell renderers in column definitions
  3. Build custom table UI with compound components
  4. Access TanStack Table directly via table._tanstackTable

​
Example: Custom Row Styling

import { SeizenTable } from '@izumisy/seizen-table';
import './custom-styles.css';

function App() {
  const table = useSeizenTable({ data, columns });

  return <SeizenTable table={table} className="custom-table" />;
}

/* custom-styles.css */
.custom-table tbody tr:nth-child(even) {
  background-color: var(--szui-header-bg);
}

.custom-table tbody tr:hover {
  transform: scale(1.01);
  box-shadow: 0 2px 8px rgba(0, 0, 0, 0.1);
  transition: all 0.2s ease;
}
CSS Variables make it easy to implement theming without learning a complex styling API. Simply define the variables you want to customize, and the rest will use sensible defaults.
