Having problems with the table helper

[eluser]sundancekid[/eluser]
Hi, I'm new to CI and just playing around with it trying to figure it out. Anyhow, I tried an example given in the user guide for generating a table from a database query, but it doesn't work for me.

I am trying this:

Code:

$this->load->library('table');

$query = $this->db->query("SELECT * FROM my_table");

echo $this->table->generate($query);

But I get this error:

Code:

A PHP Error was encountered

Severity: 4096

Message: Object of class stdClass could not be converted to string

Filename: libraries/Table.php

Line Number: 270

I know the db settings are correct I can loop through the query and display the results. The table I'm querying has about 5 fields and 3 rows.

Thanks for any help and I lookforward to learning more about CI and getting to know the community here.
