Features

• Dynamic Row Heights: Support for TextOverflow.visible with external height calculation via calculateRowHeight callback and TableRowHeightCalculator utility.
• Dynamic Scrollbar Visibility: Scrollbars are now dynamically shown or hidden based on content overflow, providing a cleaner UI when not needed.
• Synchronized Scrolling: Header and body scroll horizontally in perfect sync.
• Advanced Theming: Deeply customize headers, rows, and scrollbars. Use decoration for advanced header styling, fine-tune row interaction effects, and control the last row's bottom border with lastRowBorderBehavior.
• Flexible Data Handling: Use the rowIdKey property to specify a custom unique identifier for your rows, removing the need for a mandatory 'id' key.
• Column Sorting: Supports multi-state sorting (ascending, descending, none) with a configurable sort cycle.
• Merged Rows: Visually group and merge multiple data rows into a single unit for specific columns, supporting custom content, selection, and editing within merged cells.
• Expandable Summary Rows: Add collapsible summary rows to merged groups that can display calculated totals, counts, or any custom aggregated data.
• Hover Buttons: Interactive action buttons that appear on row hover, with customizable positioning, styling, and behavior through comprehensive theme system.
• Row Selection & Editing: Enable row selection and cell editing simultaneously, now fully compatible with merged rows. Supports double-tap and secondary-tap events on rows.
• Column Reordering: Easily reorder columns with drag-and-drop.
• Column Visibility: Dynamically show or hide individual columns.
• Smart Text Handling: Control text overflow (ellipsis, clip, visible). Tooltips for both cells and headers can be configured to appear always, only when text overflows, or never, giving you precise control over user feedback. Use tooltipFormatter for custom text content or tooltipBuilder for rich widget-based tooltips with intelligent positioning.
• Custom Cell Widgets: Render any widget inside a cell using cellBuilder for maximum flexibility.
• Conditional Feature Control: Dynamically enable/disable features like sorting and column reordering based on user permissions or application state.
• Code Refinements: Removed deprecated code and updated to the latest syntax for improved maintainability and performance.

Installation

Add this to your package's pubspec.yaml file:

dependencies:
  flutter_table_plus: ^1.16.4

Then, run flutter pub get in your terminal.

Quick Start

Get up and running with a basic table in just a few lines:

import 'package:flutter/material.dart';
import 'package:flutter_table_plus/flutter_table_plus.dart';

class QuickStartExample extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    // 1. Define your columns
    final columns = [
      TablePlusColumn(key: 'id', label: 'ID', width: 80),
      TablePlusColumn(key: 'name', label: 'Name', width: 150),
      TablePlusColumn(key: 'email', label: 'Email', width: 200),
    ];

    // 2. Prepare your data (each map must have a unique ID)
    final data = [
      {'id': 1, 'name': 'John Doe', 'email': '[e-mail]'},
      {'id': 2, 'name': 'Jane Smith', 'email': '[e-mail]'},
      {'id': 3, 'name': 'Bob Johnson', 'email': '[e-mail]'},
    ];

    // 3. Create the table
    return Scaffold(
      appBar: AppBar(title: Text('My Table')),
      body: FlutterTablePlus(
        columns: columns,
        data: data,
        rowIdKey: 'id', // Specify the key for unique row IDs
      ),
    );
  }
}

That's it! You now have a fully functional table with synchronized scrolling and responsive column widths.

Key Features with Examples

🎯 Column Sorting

Enable sorting with just a few properties:

FlutterTablePlus(
  columns: [TablePlusColumn(key: 'name', label: 'Name', sortable: true)],
  data: data,
  sortColumnKey: _sortColumnKey,
  sortDirection: _sortDirection,
  onSort: (columnKey, direction) {
    setState(() {
      _sortColumnKey = columnKey;
      _sortDirection = direction;
      // Sort your data here
    });
  },
)

☑️ Row Selection

Enable row selection with checkboxes. Supports both single and multiple selection modes.

FlutterTablePlus(
  isSelectable: true,
  rowIdKey: 'user_uuid', // Use your custom ID key
  selectedRows: _selectedRows,
  onRowSelectionChanged: (rowId, isSelected) {
    setState(() {
      isSelected ? _selectedRows.add(rowId) : _selectedRows.remove(rowId);
    });
  },
)

🎨 Advanced Theming

Customize every aspect of the table appearance. Leave interaction colors null to use the default framework effects.

FlutterTablePlus(
  theme: TablePlusTheme(
    headerTheme: TablePlusHeaderTheme(
      height: 56,
      decoration: BoxDecoration(
        color: Colors.blue.shade100,
        border: Border(bottom: BorderSide(color: Colors.blue.shade300, width: 2)),
      ),
    ),
    bodyTheme: TablePlusBodyTheme(
      rowHeight: 48,
      alternateRowColor: Colors.grey.shade50,
      selectedRowColor: Colors.blue.withValues(alpha: 0.2),
      hoverColor: Colors.blue.withValues(alpha: 0.05), // Custom hover color
      splashColor: null, // Use default splash effect
      selectedRowSplashColor: Colors.transparent, // Disable splash for selected rows
    ),
  ),
)

🔄 Column Reordering

Enable drag-and-drop column reordering:

FlutterTablePlus(
  onColumnReorder: (oldIndex, newIndex) {
    setState(() {
      // Reorder your columns list here
      final column = _columns.removeAt(oldIndex);
      _columns.insert(newIndex, column);
    });
  },
)

📏 Dynamic Row Heights

Support TextOverflow.visible with proper height calculation:

final columns = [
  TablePlusColumn(
    key: 'description',
    label: 'Description',
    width: 300,
    textOverflow: TextOverflow.visible, // Enable text wrapping
  ),
];

FlutterTablePlus(
  columns: Map.fromEntries(columns.map((col) => MapEntry(col.key, col))),
  data: data,
  // Add dynamic height calculation
  calculateRowHeight: TableRowHeightCalculator.createHeightCalculator(
    columns: columns,
    columnWidths: columns.map((col) => col.width).toList(),
    defaultTextStyle: TextStyle(fontSize: 14),
    minHeight: 48.0,
  ),
)

💬 Custom Tooltip Content

Create rich, contextual tooltips using complete row data. Choose between text-based (tooltipFormatter) or widget-based (tooltipBuilder) tooltips:

Text-Based Tooltips

TablePlusColumn(
  key: 'employee_name',
  label: 'Employee',
  width: 150,
  tooltipFormatter: (rowData) {
    return '''Employee Details:
👤 Name: ${rowData['name']}
🏢 Department: ${rowData['department']}
💼 Position: ${rowData['position']}
📧 Email: ${rowData['email']}''';
  },
),

Rich Widget Tooltips

Create interactive tooltips with any Flutter widget, featuring intelligent positioning:

TablePlusColumn(
  key: 'employee_name',
  label: 'Employee',
  width: 150,
  tooltipBuilder: (context, rowData) {
    return Container(
      width: 280,
      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: [
          ListTile(
            leading: CircleAvatar(
              backgroundImage: NetworkImage(rowData['avatar_url']),
            ),
            title: Text(rowData['name']),
            subtitle: Text(rowData['position']),
          ),
          Row(
            mainAxisAlignment: MainAxisAlignment.spaceEvenly,
            children: [
              TextButton.icon(
                onPressed: () => _sendMessage(rowData['id']),
                icon: Icon(Icons.message, size: 16),
                label: Text('Message'),
              ),
              ElevatedButton.icon(
                onPressed: () => _viewProfile(rowData['id']),
                icon: Icon(Icons.person, size: 16),
                label: Text('Profile'),
              ),
            ],
          ),
        ],
      ),
    );
  },
),

You can also create conditional tooltips based on data values:

TablePlusColumn(
  key: 'status',
  label: 'Status',
  tooltipFormatter: (rowData) {
    final isActive = rowData['active'] as bool;
    final lastLogin = rowData['last_login'] as DateTime?;
    
    return '''Status: ${isActive ? '✅ Active' : '❌ Inactive'}
Last Login: ${lastLogin?.toString() ?? 'Never'}
Access: ${isActive ? 'Full Access' : 'Restricted'}''';
  },
)

Conditional Feature Control

You can dynamically enable or disable features based on your application's needs:

FlutterTablePlus(
  // Enable features based on user permissions
  onSort: userCanSort ? _handleSort : null,
  onColumnReorder: userCanReorderColumns ? _handleColumnReorder : null,
  isSelectable: userCanSelectRows,
  isEditable: userCanEditCells,
);
