Ember Resizable Table

Ember Resizable Table is a table component for Ember.js apps that allows users to resize the table's cells by dragging its borders. It's useful for creating split panels (i.e. for code editors).

Installation

To install Ember Resizable Table, simply run:

ember install ember-resizable-table

at the root of your Ember CLI project.

Demo Application

A demo is available here

The demo uses the code from the tests/dummy folder of this addon: https://github.com/eshirazi/ember-resizable-table/tree/master/tests/dummy.

Usage Example

A simple usage of a table with colorful table cells (this is the code for creating the animated illustration above):

.hbs:

{{#resizable-table class="main-table" as |table|}}
  {{#table.tr as |row|}}
    {{row.td class="color1" rowSpan=2}}
    {{row.td class="color2"}}
    {{row.td class="color3"}}
  {{/table.tr}}
  {{#table.tr as |row|}}
    {{row.td class="color4" rowSpan=2 colSpan=2}}
  {{/table.tr}}
  {{#table.tr as |row|}}
    {{row.td class="color5"}}
  {{/table.tr}}
{{/resizable-table}}

.css:

.main-table {
  width: 400px;
  height: 400px;
  border-collapse: collapse;
}

.main-table td {
  border: 3px solid #fff;
}

.color1 {  background: #0074D9; }
.color2 {  background: #FF4136; }
.color3 {  background: #85144b; }
.color4 {  background: #39CCCC; }
.color5 {  background: #01FF70; }

Initial Column and Row Sizes

It's also possible to customize initial row and column sizes via the optional initialColumnSizes and initialRowSizes attributes. The following example uses the Ember Array Helper:

{{#resizable-table class="main-table"
    initialRowSizes=(array 0.5 0.25 0.25) 
    initialColumnSizes=(array 0.25 0.5 0.25) as |table|}}
  ...
{{/resizable-table}}

Events

Event listeners are built to trigger Ember actions on component interactions and events. To add an event listener, simply add an event attribute:

{{#resizable-table 
  onSizeChanged=(action "onSizeChanged")
  class="main-table" as |table|}}
  ...
{{/resizable-table}}

onSizeChanged(columnOrRow, index, newSize)

Triggered whenever any column or row is resized.

columnOrRow - Determines whether a row or a column was resized. The only possible values are "column", "row".
index - A zero based index of the column or row that was resized.
newSize - The new size of the row or column as a fraction of the table size - a value between 0 and 1.
