I'm creating a page that has 2 tables inside a table, the problem I'm having is that my one table doesn't go 100%, I've created a jsfiddle for you to see and the one that is the problem is the one that has a pink background. This problem only occurs in Chrome, Safari and IE, but it works just fine in Firefox.
my html
<table class="table company_table_wrapper">
<tbody>
<tr>
<td class="company_table" height="100%">
<table class="table table_unit" style="height:100%">

<td colspan="3">
<div class="company_title">
