How to save HTML data into SQL post_content column

Question

I have a custom template file containing some HTML tags and get_post_meta function. I want to insert the HTML data into post_content column. Is there a wordpress function or SQL function to save into post_content column? I couldn't find a good anwswer on the internet.
This is my custom template file.

<?php
    // the post name is cryto name.
    $cryto_name = get_the_title();

    // Cryto Variables from SQL table
    $ccf_company = get_post_meta( get_the_ID(), 'ccf_company', true );
    $ccf_jurisdiction = get_post_meta( get_the_ID(), 'ccf_jurisdiction', true );
    $ccf_symbol = get_post_meta( get_the_ID(), 'ccf_symbol', true );
    $ccf_maximum_supply = get_post_meta( get_the_ID(), 'ccf_maximum_supply', true );

?>

<h2>Features of <?php echo $cryto_name ?></h2>

<figure class="ht-post__content table">
    <table>
        <thead>
            <tr>
                <th>Features</th>
                <th class="has-text-align-center" data-align="center"><?php echo $cryto_name ?> (<?php echo $ccf_symbol ?>)</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>Developer</td>
                <td class="has-text-align-center" data-align="center"><?php echo $ccf_company ?></td>
            </tr>
            <tr>
                <td>Country</td>
                <td class="has-text-align-center" data-align="center"><?php echo $ccf_jurisdiction ?></td>
            </tr>
            <tr>
                <td>Symbol</td>
                <td class="has-text-align-center" data-align="center"><?php echo $ccf_symbol ?></td>
            </tr>
            <tr>
                <td>Max Supply</td>
                <td class="has-text-align-center" data-align="center"><?php echo check_max_supply($db_coin_max_supply, $ccf_symbol) ?></td>
            </tr>
    </table>
</figure>

I already made a sql table and this template is working. However, I'm trying to save this HTML output into post_content column.
