Control Panel/MCP: Table class in older versions of EE2

Question

Have there been any changes to the table class in EE2? I have a bug report on an add-on from a user with EE v2.3.1. They've received the following error in my mcp. file:

<b>Fatal error:</b> Call to undefined method CI_Table::set_columns()

My code looks like this, nothing looks amiss:

$this->EE->load->library('table');
$this->EE->table->set_columns(array(
    // column mappings
));

And things work fine in 2.5.5. Here's the EE documentation I relied on:

Thanks for any insight you can offer!

Answer 1

I just checked, and the EE_Table class, as well as the EE_Table::set_columns() method were introduced in EE 2.4.0.

Before that, EE only included the default CodeIgniter (v2.0.1) table class.
