Columns in shop page

Do you want no columns displayed, or do you want sidebars on it?

You can use this function:

add_filter( 'generate_sidebar_layout','generate_custom_woocommerce_sidebar_layout' );
function generate_custom_woocommerce_sidebar_layout( $layout )
{
 	// If we are on a woocommerce page, set the sidebar
 	if ( is_woocommerce() )
 	 	return 'both-left';

 	// Or else, set the regular layout
 	return $layout;

 }

These are the options:

Sidebar / Content: left-sidebar
Content / Sidebar: right-sidebar
Content (no sidebars): no-sidebar
Sidebar / Content / Sidebar: both-sidebars
Sidebar / Sidebar / Content: both-left
Content / Sidebar / Sidebar: both-right

Dear Tom,

I was referring to the number of product thumbnail columns in a woocommerce product archive page. I did not mean the number of sidebars.
I am sorry for not communicating my request properly
