Table class behaving differently in IE and chrome

[eluser]Unknown[/eluser]
Hi,
I am using the codeigniter table class and generating a few tables and appending it to a string.

Code:

$grid="";
$grid .=$this->table->generate();
$this->table->clear();

The tables appear in a proper fashion in Chrome (one after the other vertically) whereas in IE it is displaying horizontally. What can be done to resolve this?
