A small (2.4kb gzipped) and accessible jQuery plugin for adding sticky headers to large data tables.

Demo

https://simonsmith.github.io/jquery.stickyTableHeader/test/

Features

• Supports multiple tables on one page
• Uses position: fixed that allows smooth scrolling and a wide range of browser support
• Screenreader support
• Minimal DOM updates in scroll event

Installation

npm

It's recommended to require/import the plugin as part of an existing webpack or browserify setup:

npm install jquery jquery-sticky-table-header --save 

// index.js const $ = require('jquery'); require('jquery-sticky-table-header'); $('.table-container').stickyTableHeader();

Relies on jQuery as a peerDependency so ensure it is installed in your application.

Manual

1. Clone the repository
2. yarn && yarn run build or npm install && npm run build
3. A UMD version of the plugin will be available in the ./build directory.
4. Include it in your project as needed

Example

<script src="http://code.jquery.com/jquery-latest.js"></script> <script src="jquery.stickyTableHeader.js"></script>

Usage

There are some HTML requirements for the plugin to function correctly:

• The table must be inside a containing element with no siblings
• There must be a thead element
• There must be a tbody element

Example

<div class="table-container">   <table>     <thead>       <!-- content -->     </thead>     <tbody>       <!-- content -->     </tbody>   </table> </div>

$('.table-container').stickyTableHeader();

It's recommended that you apply a background colour to the header to mask the real table header beneath it.

Options

• outsideViewportOnly - (boolean) Only run the plugin if the table is larger than the viewport default true
• scrollThrottle - (number) Maximum number of times the scroll handler can be called over time in milliseconds default 50
• zIndex - (number) Added to the header to control stacking default 2
• offset (object) Offset values for the header
  • top (number) - Offset (in pixels) applied to the header default 0
  • topScrolling (string) - Offset (in pixels) applied to the header whilst scrolling default 0
• css (object) Classes applied to the HTML structure
  • header (string) - Added to the header that scrolls with the table default StickyTableHeader
  • scrolling (string) - Added to the header when it is scrolling with the viewport default is-scrolling
  • active (string) - Added to the original table when plugin is active default is-stickyTableHeaderActive

Methods
