Large tables cut off in flowable epub export

[NYA29759424vd7q]

I'm exporting a book from InDesign to both PDF and EPUB formats. The EPUB must be flowable, and I'm using Aquile Reader to review the output. Most of the content converts well, but a large table is getting truncated during export.

This table is critical and needs to retain its original structure. Because it's too large to fit within the two-column layout of the book, I anchored it to a section of the text that references it, rather than placing it directly inline. I've tried making the graph smaller, but that somehow made it worse.

I've included screenshots below. What's the best way to ensure the full table exports properly in the flowable EPUB format?

Rule one: keep it simple

I would not use a two-column layout for reflowable EPUB. Stick with a single column and keep the table within those bounds. Tables are not responsive and the user has too many options to override your fonts and font sizes so you may want to try and redesign the table, too.

If you are comfortable editing the CSS, you could specify the width of the columns in order to constrain the width.
