How can I re-install a module? I am creating on Drupal 8 module. I have used a custom table to store the data collected from forms.
Somehow during installation, tables are not created due to an issue in the install file. Now I have fixed the issue, and I want to install the module again.

How can I re-install a module?

From this and this discussions, I know the Disable module functionality has been removed. 

Is there any other way to re-install a module so that its database tables are created?
The Devel module can also help here.

It makes a "Reinstall modules" page available at /devel/reinstall, which lets you re-install modules in bulk.

It's also worth mentioning Drush; dis (obviously) doesn't work any more, but pm-uninstall and en still do. And if you have Devel installed, you can invoke a reinstall with

drush dre module1 module2
