Consider your table with title,content_heading and content field are defined,

Now you have to pass inside __consturct field to your module factory object like below, Table with below content are automatically added.

<?php
namespace Vendor\Modulename\Setup;

use Magento\Framework\Module\Setup\Migration;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;

class InstallData implements InstallDataInterface
{
    private $_postFactory;

    public function __construct(\Vendor\Modulename\Model\PostFactory $postFactory)
    {
        $this->_postFactory = $postFactory;
    }


    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $data = [
            'title' => 'Hello world!',
            'content_heading' => 'Hello world!',
            'content' => 'logn description put here'
        ];

        $this->_postFactory->create()->setData($data)->save();
    }

}
