namespace Test\TestAgain\Setup;

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

class UpgradeSchema implements UpgradeSchemaInterface
{

    /**
     * {@inheritdoc}
     */
    public function upgrade(
        SchemaSetupInterface $setup,
        ModuleContextInterface $context
    ) {
        $installer = $setup;

        $installer->startSetup();
        if (version_compare($context->getVersion(), "1.0.0", "<")) {
        //Your upgrade script
        }
        if (version_compare($context->getVersion(), '1.0.1', '<')) {
          $installer->getConnection()->addColumn(
                $installer->getTable('lime_eleveniacategory'),
                'category_depth',
                [
                    'type' => \Magento\Framework\DB\Ddl\Table::TYPE_INTEGER,
                    'length' => 10,
                    'nullable' => true,
                    'comment' => 'Category Depth'
                ]

        }
        $installer->endSetup();
    }
}

You can get more details here also, Upgrade Database table

One more thing to do here. Update module.xml version. And upgrade setup, do reindexing and delete cache. It will work.

To Add multiples columns

    if (version_compare($context->getVersion(), '0.1.1', '<')) {
        $installer->getConnection()->addColumn(
            $installer->getTable('reply_newsletter_subscriber'),
            'field_1',
            [
                'type' => \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
                'length' => 255,
                'nullable' => true,
                'comment' => 'Field_1'
            ]

        );
        $installer->getConnection()->addColumn(
            $installer->getTable('reply_newsletter_subscriber'),
            'field_2',
            [
                'type' => \Magento\Framework\DB\Ddl\Table::TYPE_TEXT,
                'length' => 255,
                'nullable' => true,
                'comment' => 'Field_2'
            ]
        );
    }
    $installer->endSetup();
}

I tried this

    <?php


namespace Test\TestAgain\Setup;

use Magento\Framework\Setup\UpgradeSchemaInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Quote\Setup\QuoteSetupFactory;
use Magento\Sales\Setup\SalesSetupFactory;
use Magento\Framework\DB\Ddl\Table;
use Magento\Quote\Setup\QuoteSetup;
use Magento\Sales\Setup\SalesSetup;

class InstallData implements InstallDataInterface
{
    protected $quoteSetupFactory;
    protected $salesSetupFactory;

    public function __construct(
        QuoteSetupFactory $quoteSetupFactory,
        SalesSetupFactory $salesSetupFactory
    ) {
        $this->quoteSetupFactory = $quoteSetupFactory;
        $this->salesSetupFactory = $salesSetupFactory;
    }

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
         $quoteInstaller = $this->quoteSetupFactory->create(['resourceName' => 'quote_setup', 'setup' => $setup]);
         $salesInstaller = $this->salesSetupFactory->create(['resourceName' => 'sales_setup', 'setup' => $setup]);

        $setup->startSetup();

        $setup->startSetup();
        $quoteInstaller->addAttribute('quote', 'custom_column', ['type' => Table::TYPE_TEXT]);
        $salesInstaller->addAttribute('order', 'custom_column', ['type' => Table::TYPE_TEXT]);
        $setup->endSetup();


        }
}

OR

<?php


namespace Test\TestAgain\Setup;

use Magento\Framework\Setup\UpgradeSchemaInterface;
use Magento\Framework\Setup\SchemaSetupInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Quote\Setup\QuoteSetupFactory;
use Magento\Sales\Setup\SalesSetupFactory;
use Magento\Framework\DB\Ddl\Table;
use Magento\Quote\Setup\QuoteSetup;
use Magento\Sales\Setup\SalesSetup;

class UpgradeSchema implements UpgradeSchemaInterface
{


    public function upgrade(SchemaSetupInterface $setup, ModuleContextInterface $context)
    {


         $installer = $setup;
        $installer->startSetup();
        $connection = $installer->getConnection();
        $connection->addColumn($installer->getTable('quote'), 'custom_column', [
            'type'     => Table::TYPE_TEXT,
            'nullable' => true,
            'comment'  => 'Custom Column Name'
        ]);
        $connection->addColumn($installer->getTable('sales_order'), 'custom_column', [
            'type'     => Table::TYPE_TEXT,
            'nullable' => true,
            'comment'  => 'Custom Column Name'
        ]);

        $installer->endSetup();


        }
}

Note: If you face any issue, it may be due to the module that you have already installed. As you know, if the module is already installed then setup:upgrade command does not install schema. You will need to look into your setup_module table, delete your module from the table and re-run the php bin/magento setup:upgrade command.
