Hi,
Please add the content to WordPress default editor, I found that you have added it.
To hide the Tabs of Woo, please add the custom CSS to “Appearance > Customize: Additional CSS”

.single-product #product-tab {
    display: none;
}

For the 2 columns layouts, you can create by a shortcodes plugin like https://wordpress.org/plugins/shortcodes-ultimate/
The columns shortcodes of Shortcodes Ultimate should be:

[su_row class=""]
[su_column size="3/4" center="no" class=""]content xxx xx xxx[/su_column]
[su_column size="1/4" center="no" class=""]<img src="xxx.png"  width="100" />[/su_column]
[/su_row]

Regards!
