Notes

⚙️ DataTables Key Extensions (Quick Reference)

📋 KeyTable

Navigate/select individual table cells (Excel-style).

Great for keyboard-based data entry.

🔁 AutoFill

Drag to duplicate or increment data like spreadsheets.

🧾 Buttons

Built-in buttons for export & copy:

🧠 copy → Copy to clipboard
📁 csv → Export to CSV
📊 excel → Export to XLSX (requires JSZip)
📄 pdf → Export to PDF (requires PDFMake)
🖨️ print → Print table

💡 HTML5 Variants:

copyHtml5, csvHtml5, excelHtml5, pdfHtml5

(Use generic ones; they auto-detect browser capabilities.)

Custom Buttons:

text: label text
action: function to execute on click

Example: Add your own “Reload” or “Sync” button.

👁️‍🗨️ Column Visibility (colvis)

Toggle visibility of single or grouped columns.
Makes tables user-customizable and tidy.

🧭 ColReorder

Drag & drop to reorder columns freely.

🧰 ColumnControl

Adds per-column search/sort/filter controls in headers/footers.
Extendable with plugins for custom inputs.

⚡ Server-Side Processing (`serverSide: true`)

For large datasets (100k+ rows) — loads only visible data via AJAX.
Client sends filters/paging/sorting state to server → server returns relevant rows.

Essential for performance-heavy dashboards.

✏️ Editor (CRUD made easy)

Powerful inline data editing tool:

🧍‍♀️ Full Row Editing: Modal form for entire row
💬 Bubble Editing: Quick popup for specific cells
⚡ Inline Editing: Click → Type → Enter (super fast)

👉 Use generator: editor.datatables.net/generator

📌 FixedColumns

Keep left/right columns visible while horizontally scrolling (scrollX: true).

For non-scrollable tables, use FixedHeader.

📍 FixedHeader

Sticky headers/footers for long tables.
Keeps column labels visible during scroll.

📱 Responsive

Adapts layout for smaller screens.
Hides non-essential columns, adds expandable rows.

Crucial for mobile/tablet optimization.

👥 RowGroup

Group rows by a specific column value (like categories).
Customize group headers and footers.

⚠️ Limitations:

No expand/collapse
Only single-level grouping
Not compatible with Scroller or Buttons exports yet

↕️ RowReorder

Drag-and-drop rows to reorder.
Works even with non-sequential data.
Can sync changes with Editor for DB updates.

🚀 Scroller

Virtual rendering for huge datasets.
Renders only visible rows (smooth scrolling, fast performance).

For millions of records, this is a must.

🔍 SearchBuilder

Build complex “AND / OR” search queries visually.
Auto-detects column data types and filters accordingly.
Extendable for custom logic.

🔎 SearchPanes

Add filter panes for quick visual filtering.
Multi-pane, multi-value searches.

Easier for users than typing queries manually.

✅ Select

Enables selection of rows, columns, or cells.
Selection modes:
- os (Windows-like: Ctrl + click, Shift + click)
- single, multi, multi+shift
Full API: rows().select(), cells().select(), etc.
Integrates with Buttons for “Select all / Deselect all”.

💾 StateRestore

Save & reload multiple DataTable states (filters, layout, pages).
Store locally or via AJAX for user sessions.

🗓️ DateTime

Built-in date/time picker (used by Editor & SearchBuilder).
Integrates with Moment.js, Luxon, or Day.js.

$('#myTable').DataTable( { keys: true, autoFill: true, colReorder: true, fixedColumns: true, fixedHeader: true, responsive: true, rowReorder: true, ajax: '/api/data', scrollY: 200, deferRender: true, scroller: true, select: true, columnControl: ['order', ['orderAsc', 'orderDesc', 'search']], buttons: [ { extend: 'pdfHtml5', title: '<?= $heading; ?>', text: 'PDF', titleAttr: 'Generate PDF', className: 'btn-outline-danger btn-sm mr-1', exportOptions: { columns: ':visible' } // to download only visible columsn using colvis }, { extend: 'excelHtml5', title: '<?= $heading; ?>', text: 'Excel', titleAttr: 'Generate Excel', className: 'btn-outline-success btn-sm mr-1' }, { extend: 'csvHtml5', title: '<?= $heading; ?>', text: 'CSV', titleAttr: 'Generate CSV', className: 'btn-outline-primary btn-sm mr-1' }, { extend: 'copyHtml5', title: '<?= $heading; ?>', text: 'Copy', titleAttr: 'Copy to clipboard', className: 'btn-outline-primary btn-sm mr-1' }, { extend: 'colvis', title: '<?= $heading; ?>', text: 'colvis', titleAttr: 'select columns', className: 'btn-outline-primary btn-sm mr-1' }, { extend: 'print', text: 'Print', titleAttr: 'Print Table', title: '<?= $heading; ?>', customize: function (win) { $(win.document.body).find('h1').css('text-align', 'center'); $(win.document.body).css('font-size', '9px'); $(win.document.body).find('table') .addClass('compact') .css('font-size', 'inherit'); }, className: 'btn-outline-primary btn-sm' }, //custom button { text: 'Reload', action: function ( e, dt, node, config ) { dt.ajax.reload(); } ], rowGroup: { dataSrc: 'group' }, } );
