Currency Format Comparison - Choose Your Format

The same salary data displayed in three different formats. You choose which formatter to use for each column!

Three Currency Formatters Available:

  • formatCurrency - Standard with commas, no decimals (e.g., £75,000)
  • formatCurrencyDecimals - With commas AND decimals (e.g., £75,000.00)
  • formatCurrencyCompact - With K/M abbreviations (e.g., £75K)

Each column below uses a different formatter on the same salary data. You can use different formats in different columns based on your needs!

How to Use Different Formatters:

import { formatCurrency, formatCurrencyDecimals, formatCurrencyCompact } from '$lib/dataGridFormatters';

const columns: DataGridColumn[] = [
  {
    id: 'annualBudget',
    header: 'Annual Budget',
    formatter: formatCurrencyCompact  // ← Use compact for large numbers (£1.5M)
  },
  {
    id: 'productPrice',
    header: 'Product Price',
    formatter: formatCurrencyDecimals  // ← Use decimals for precise prices (£12.99)
  },
  {
    id: 'totalRevenue',
    header: 'Total Revenue',
    formatter: formatCurrency  // ← Use standard for whole numbers (£75,000)
  }
];

Usage Guide

Column Styling & Formatting

<script>
  import DataGridBasic from '$lib/components/DataGridBasic.svelte';
  import {
    formatCurrencyCompact,
    createGradientStyle,
    createStatusBadge,
    createIconRenderer
  } from '$lib/dataGridFormatters';

  const columns = [
    {
      id: 'salary',
      header: 'Salary',
      type: 'number',
      formatter: formatCurrencyCompact, // £75K, £1.5M
      cellStyle: createGradientStyle(30000, 150000, '#ef4444', '#22c55e')
    },
    {
      id: 'status',
      header: 'Status',
      cellRenderer: createStatusBadge({

DataGridFilters - Advanced Filtering

<script>
  import DataGridFilters from '$lib/components/DataGridFilters.svelte';
  import DataGridAdvanced from '$lib/components/DataGridAdvanced.svelte';

  let filters = $state({
    departments: [],
    statuses: [],
    salaryMin: 30000,
    salaryMax: 150000,
    hireDateFrom: '',
    hireDateTo: ''
  });

  const filteredData = $derived(() => {
    return data.filter(employee => {
      // Apply filter logic
      return true;
    });
  });
</script>

<DataGridFilters
  departments={ ['Engineering', 'Sales', 'Marketing'] }
  statuses={ ['active', 'on-leave'] }
  salaryRange={ { min: 30000, max: 150000 } }
  onFiltersChange={ (newFilters) => filters = newFilters }
/>

<DataGridAdvanced
