short but sweet: Grid in magento 2

1. Create registration.php file.
-----------------------------------------------
<?php

\Magento\Framework\Component\ComponentRegistrar::register(
\Magento\Framework\Component\ComponentRegistrar::MODULE,
'Krupa_Customcontact',
__dir__
);

2. Define module.xml file. in etc directory
---------------------------------------------------------------
<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNameSchemaLocation ="urn:magento:framework:Module/etc/module.xsd">
<module name="Krupa_Customcontact" setup_version="2.2.2">
<sequence>
<module name="Magento_Contact"/>
</sequence>
</module>
</config>

3. Create setup script (setup/InstallSchema.php)
-------------------------------------------------------------
<?php
namespace Krupa\Customcontact\Setup;

use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\SchemaSetupInterface;

class InstallSchema implements \Magento\Framework\Setup\InstallSchemaInterface {

public function install(
SchemaSetupInterface $setup,
ModuleContextInterface $context
) {
$installer = $setup;

$installer->startSetup();

$table = $installer->getConnection()
->newTable($installer->getTable('customcontact'))
->addColumn(
'entity_id',
\Magento\Framework\DB\Ddl\Table::TYPE_INTEGER,
null,
['identity' => true, 'unsigned' => true, 'nullable' => false, 'primary'=>true ],
'Entity Id'
)
->addColumn(
'name',
\Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
150,
['unsigned'=>true, 'nullable' => false],
'Name'
)
->addColumn(
'email',
\Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
150,
['nullable' => false],
'Email'
)
->addColumn(
'telephone',
\Magento\Framework\DB\Ddl\Table::TYPE_INTEGER,
null,
['unsigned'=>true, 'nullable' => false],
'Telephone'
)
->addColumn(
'comment',
\Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
'64K',
['nullable' => false],
'Comment'
)
->setComment('Custom Contact');

$installer->getConnection()->createTable($table);

$installer->endSetup();
}

}

4. Create a front end router (etc/frontend/routes.xml)
----------------------------------------------
<?xml version="1.0" ?>

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:App/etc/routes.xsd">
<router id="standard">
<route id="customcontact" frontName="customcontact">
<module name='Krupa_Customcontact'/>
</route>
</router>
</config>

5. Create a front end Di.xml file
------------------------------------------------
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

<type name="Magento\Contact\Controller\Index\Post">
<plugin name="custom_contact_action" type="Krupa\Customcontact\Plugin\Post"/>
</type>
</config>

6. create a Plugin
----------------------------------

$contact->setTelephone($post['telephone']);
$contact->setComment($post['comment']);

$contact->save();

/* $storeScope = \Magento\Store\Model\ScopeInterface::SCOPE_STORE;
$transport = $this->transportBuilder
->setTemplateIdentifier($this->scopeConfig->getValue(\Magento\Contact\Controller\Index\Post::XML_PATH_EMAIL_TEMPLATE, $storeScope))

->setReplyTo($post['email'])
->getTransport();

$transport->sendMessage();
$this->inlineTranslation->resume();*/
$this->messageManager->addSuccess(
__('Thanks for contacting us with your comments and questions. We\'ll respond to you very soon.')
);
return $this->resultRedirectFactory->create()->setPath('customcontact/index/index');
} catch (\Exception $e) {
//$this->inlineTranslation->resume();
$this->messageManager->addError(
__('We can\'t process your request right now. Sorry, that\'s all we know.')
);
return $this->resultRedirectFactory->create()->setPath('customcontact/index/index');
}
}
}

7. create a front controller index action
--------------------------------------------------------
<?php
namespace Krupa\Customcontact\Controller\Index;
