Installation

Using Bower

This package is installable through the Bower package manager.

bower install angular-fixed-table-header --save

In your index.html file, include the source file.

<script type="text/javascript" src="bower_components/angular-fixed-table-header/src/fixed-table-header.min.js"></script>

Include the fixed.table.header module as a dependency in your application.

angular.module('myApp', ['fixed.table.header']);

Using npm and Browserify (or JSPM)

In addition, this package may be installed using npm.

npm install angular-fixed-table-header --save

You may use Browserify to inject this module into your application.

angular.module('myApp', [require('angular-fixed-table-header')]);

Usage

Wrap the table in a element that will scroll vertically. Use the fix-head attribute on a <thead> element to prevent it from scrolling with the rest of the table.

A clone of the original <thead> element will be moved outside the scroll container. To ensure valid HTML, the cloned <thead> element will be wrapped in a copy of the <table> element. The new <table> element will be given the clone class.

<div style="overflow: auto; max-height: 300px;">
  <table>
    <thead fix-head>
      <tr>
        <th>Name</th>
        <th>City</th>
        <th>State</th>
        <th>Zip</th>
        <th>Email</th>
        <th>Phone</th>
      </tr>
    </thead>
    <tbody>
      <tr ng-repeat="contact in contacts">
        <td>{{contact.name}}</td>
        <td>{{contact.city}}</td>
        <td>{{contact.state}}</td>
        <td>{{contact.zip}}</td>
        <td>{{contact.emial}}</td>
        <td>{{contact.phone}}</td>
      </tr>
    </tbody>
  </table>
</div>

Change Log

Version 0.2.1

March 15, 2016

Set the max width of the header cell as well.
Fix bower.json main property.

Version 0.2.0

March 4, 2016

You may now use ng-repeat within the table header.

How It Works

Clone the original <table> element and empty its contents, then move it outside the scroll container and compile it.
Clone the original <thead> element and append it to the original <table> element and compile it.
Detach the cloned <thead> element and append it to the cloned <table> element.
For each <th> in the cloned <thead>, set its width equal to the width of the original <th> in the original <thead>.
Set the top margin of the original <table> element equal to negative the height of the original <thead> element.
When the scroll container is scrolled horizontally, use css transforms to translate the cloned <thead> element.

The advantage of this solution is the functionality of HTML tables is preserved.

Restrictions

Your table must be wrapped in a div that determines the vertical scroll of your table (you may use flex box).
You may only have one thead element; however, your thead element may have multiple rows.

Using With The Data Table Module

If you are using this directive with my data table module then be aware that the progress indicator will still scroll with the rest of the table.

Use the following CSS to correct the borders.

table.clone thead tr:last-child th {
  border-bottom: 1px rgba(0, 0, 0, 0.12) solid;
}

table.clone + md-table-container table tbody tr:first-child td {
  border-top: none;
}

Why Not?

Why not reposition the original header instead of making a clone?

I'm taking advantage of the browsers ability to calculate the width of the columns. Otherwise the developer would have to manually set the width of each column like many other solutions.

Why not use a pure CSS solution?

CSS solutions often defeat the purpose of using a table in the first place. In addition, the solutions I've seen remove functionality from the table and require the developer to manually set the width of each column.
