Once this plugin is activated, you’ll be able to use the new “shortcodes” 
in your sidebar text widget. The shortcodes will work exactly the same 
way as they do in your posts.

Adds shortcodes to easily create columns in your posts or pages.
Sometimes you just need to divide your page into different columns. With this plugin you just select a column shortcode and it will add the column to the page. You can also change the padding of each individual column from the UI.
There are 10 different column widths available from which you can make all combinations:
<ul>
<li>full width (1/1)</li>
<li>half (1/2)</li>
<li>one third (1/3)</li>
<li>two third (2/3)</li>
<li>one fourth (1/4)</li>
<li>three fourth (3/4)</li>
<li>one fifth (1/5)</li>
<li>two fifth (2/5)</li>
<li>three fifth (3/5)</li>
<li>four fifth (4/5)</li>
<li>one sixth (1/6)</li>
<li>five sixth (5/6)</li>
</ul>
A preset stylesheet is included, which you can also overwrite to you liking in your theme’s stylesheet.
