JarCastingangular-responsive-tables
Make your HTML tables look great on every device. Compatible with AngularJS 1.3.4+.
Why?
Currently, browsers for mobile devices like smartphones doesn't do anything to have a proper presentation of tables, and then scrollbars will show up and ruin your design.
In the search of a solution to this problem I have found many different approaches. Some of them still rely on horizontal scrollbars. While I believe this layout could be useful for some use cases, I felt that a default solution should avoid horizontal scrollbars entirely. Then I came up with this highly reusable directive.
All this work is based on the following assumptions:
- If it is flexible, then it would solve most problems, even ones not aimed by the library author's;
- Focusing on the task of adding responsiveness, in order to accomplish a greater objective (easy to use tabular data);
- Do work with a standard HTML table, not requiring any extraneous markup;
- Do not change default tabular layout unless a smaller display is detected;
- Provide convenience without sacrificing flexibility;
- By keeping code base simple, it is easier to reason about and evolve;
- By fully covering with tests, it can evolve without introducing bugs.
Features
- Angular native implementation compatible with 1.3.4+;
- Keep things DRY;
- Supports static and dynamic (ng-repeat) rows;
- Supports conditionally shown (ng-if) columns;
- Supports dynamic headers (ng-repeat);
- Supports nested tables (responsive or not in their own right);
- Easy to apply any style on top of it;
- Works with any base CSS framework;
- Should integrate seamlessly with any table component you might choose to use.
Future Work
- Choose what columns to show/hide according to a given screen resolution;
- Choose when it would be best to hide columns or collapse all columns;
- Define a header and/or custom template for collapsed columns/row;
- Allow collapse/expand column details.

<td>...</td>
</tr>
<tr>
<td>...</td>

Directives
wt-responsive-table
- table: wt-responsive-table
- td: responsive-omit-title: title should be ommited
- td: responsive-omit-if-empty: no row for empty cells
- td: data-title: use to override the header for a given row/cell
Installation
npm
npm install --save angular-responsive-tables
Bower
bower install angular-responsive-tables --save
Application
HTML
<link rel="stylesheet" href="release/angular-responsive-tables.min.css">
<script type="text/javascript" src="release/angular-responsive-tables.min.js"></script>
JavaScript
var app = angular.module('app', ['wt.responsive']);
Special cases
Header doesn't appear for a row / need to override header
It's possible to override a header with a data-title attribute:
<tr>
<td data-title="column 1">tom</td>
<td data-title="column 2">jerry</td>
</tr>
Changes to header text doesn't reflect in responsive mode
This is by design. To avoid expensive digest cycles only the content from the first digest cycle is used. There are no watchers being setup.
Dynamic column names
When loading column names with an asynchronous task, that is, column names are not available when first compiling the table element, rows in responsive mode won't have headers even after the task completes.
To avoid this problem, use an ng-if to conditionally present the element on screen.
<table wt-responsive-table ng-if="columnNames && columnNames.length">
IE9 responsive hack
Because IE9 doesn't handle correctly a display CSS rule for <td>, if you need to support it, you can use the following style, only for IE9:
<!--[if IE 9]>
<style>
/* rules for IE9 only */
.responsive {
overflow: hidden;
}
.responsive td:nth-child(odd), .responsive td:nth-child(even) {
float: left;
width: 100%;
}
</style>
