Can't create table when installing module
Follow the standard procedure to unisntall a module.

In short, once the module is disabled it may appear in the Uninstall tab of the modules page. Select the module in that tab and click 'Uninstall'. 

When you disable a module its configuration and tables are kept, so if you enable again all data and configuration remains the same. When you uninstall a module you tell Drupal to wipe out any configuration and data by that module. When enabling it again Drupal detects that there's no configuration nor tables of that module and creates them again. If you only disable the module and enable it Drupal doesn't create configuration and tables because they should be in the database,m as Drupal knows module was enabled once.

In module list you have the available modules, some them enabled and some them disabled. If oyu want to comnpletely remove a module you have to disable, uninstall and delete the folder manually.
