Honestly? Don't use an app for this. Dawn (and most OS 2.0 themes) has a collapsible row block on the product template. Make a metafield on the product called size_chart (rich text or a page reference), put your table in there, and add a collapsible row block that shows the metafield. Assign a different chart per collection via bulk editor.
Zero apps, zero monthly fee, loads instantly, survives theme updates. Takes about 30 minutes the first time. Happy to write it up in more detail if useful.

Short version:
1. Settings → Custom data → Products → Add definition. Name it Size chart, type Rich text.
2. On each product (or via bulk editor / a CSV), paste your table into the field.
3. Theme editor → product template → Add block → Collapsible row. In the block's content field, click the dynamic source icon and pick your Size chart metafield.
4. Set the heading to "Size guide".
If you want a popup instead of an accordion you'd need a tiny bit of Liquid, but the accordion converts about the same in my experience.
