html table library does not load

[eluser]motsan[/eluser]
Tried this morning,

Same result : error, function call on non object...set_template...
with autoload file having 'table' in array and user in model autoload array

in my controller :
function index() {
$this->table->set_template($tmpl);
...
}

I have some config that may cause problem in my Application developpment based on CI, I will try with fresh install of CI 1.6.1 and post here
