How to show this table in collapsible content in dawn theme without creating pages. As i have to show different size guide in each product.
You can create Product metafields which takes file as content type. For each of your product you just upload the relevant file against it.
However, I think the default collapsible row in Dawn does not allow you to connect dynamic source such as file or image in the row content. You can add a custom liquid type to the collapsible row and then render the metafields in the custom liquid section.
If you don’t know how to create a custom liquid section in collapsible row, I would recommend to watch this YouTube tutorial: https://www.youtube.com/watch?v=sj42pjgpEmc
