This plugin is currently aimed at developers so it doesn’t come with any CSS or JavaScript, it just ads the DIVs for the columns, the rest is up to the developer’s imagination. This will allow developers to easily add column functionality to custom WordPress implementations.
<h3>Usage</h3>
How do users use it?
To split the content into columns, you simply add the shortcode [columnbreak] where you want the one column to end and the next one to start.
It will add a container around the columns with the class ‘ninja_columns’ and the class ‘colsid_{post-id}’ that will allow you to target the post or page specifically.

Ninja Columns

The plugin will allow users to easily split content into columns using short-codes.

“Manage User Columns” is a small plugin that allows you to manage the user fields displayed on the users list page in the WordPress dashboard area. 
The new fields will be added as columns with other user information. All new columns will be sortable.
You can add default user fields like registration-date, custom fields added by other plugins or custom code, and remove any default or custom field from the Users list table. 
Removing columns will not delete any user data. So, you are safe to toggle between these columns.
This plugin adds a new column “Registration Date” as a default column which you can enable/disable easily.

Manage User Columns


Sweet little thing - but does not allow to suppress these columns: Comments, Last login, Failed login attempts, Registered



So I had to install the much larger plugin (grr) "Admin Columns". Which also allows you to set the width of the columns.


Not bad, but...

This plugin allows you to manage columns under the users page in the WordPress admin area.
