HI Abimael Castro,
Thank you for your purchase.

Something like this will require some code change.

In file source/class.wdttools.php around line 381 find this line of code

'sInfo'                     => __('Showing _START_ to _END_ of _TOTAL_ entries', 'wpdatatables'),

and change it to look like this

sInfo'                     => __('Total Records _TOTAL_', 'wpdatatables'),

Let me know the result.

Best regards.
