SQL-Query to put content in categories.

[GriZzm0]

I'm learning to create plugins. And I'm working on a plugin that should print out 6 categories from the databas.

$result = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "jobs WHERE act = 1");

Then the 6 categories should be filled with content.

$resultRequest = $db->query_read("SELECT * FROM " . TABLE_PREFIX . "jobs WHERE act = 0 and category = '". $category['category'] ."' LIMIT 5");

The problem is that I have no idea how to make it print out the info inside the categories.
I would like to print it out like this.

+-----------------------+-----------------------+-----------------------+
|	Category 1	|	Category 2	|	Category 3	|
+-----------------------+-----------------------+-----------------------+
|	Content in	|	Content in	|	Content in	|
|	Category 1	|	Category 2	|	Category 3	|
+-----------------------+-----------------------+-----------------------+
|	Category 4	|	Category 5	|	Category 6	|
+-----------------------+-----------------------+-----------------------+
|	Content in	|	Content in	|	Content in	|
|	Category 4	|	Category 5	|	Category 6	|
+-----------------------+-----------------------+-----------------------+

Anyone have any idea on how to do that?
