Unfortunately, in oik version 2.0 there is an oversight regarding plugin include file dependencies. The [bw_table] shortcode attempts to use functionality which is now delivered as part of the oik-fields plugin. If you try to use this shortcode without having the oik-fields plugin also activated then you will get a Fatal error.
What you will see
If you use the [bw_table] shortcode without oik-fields activated then the following may be displayed.
Fatal error: Call to undefined function bw_theme_field() in wp-content/plugins/oik/shortcodes/oik-table.php on line 130
Note: This problem is reported on WordPress.org as
Not behaving at all in WP 3.5.2 (bw_theme_field missing)
Install and activate the oik-fields plugin.
You may remember that oik version 1.17 performed plugin relocation of any active child plugin. See oik v1.17 – plugin relocation and oik-plugins server
In oik version 2.0 all the child plugins that were previously delivered were removed. The intention was to make the oik base plugin a little leaner.
Unfortunately some of the functionality used by the [bw_table] shortcode was accidentally moved to the oik-fields plugin. This was not detected during development, since we run other plugins that have a dependency on both the oik base plugin AND oik-fields, so we almost always have the oik-fields plugin activated.
Oops, sorry for any inconvenience.
Long term solution
A fix is currently being developed to the oik base plugin. oik-fields will also be updated.
