Im doing an article that i want to have detail drop downs so readers can click on it if they want to see the deails of something.

When i use only words and preview the detail drop downs show.

When i add in an HTML so i can add in a coded table and preview the detail stuff disappears.

I used to add tables from excel in the details drop down but i was trying to make the teams look nicer with HTML.

Any reason they disappear on the preview page?

The Above is what it looks like when i edit but nothing shows after i save draft and then preview.

Im working on a post in wordpress. Im copying tables from google sheets into wordpress. While editing they look fine but when i go to preview the page or publish it. The tables are all all werid.

I have many columns but they try to fit to the page rather than extend and the columns text wrap

does anyone know how to fix that?
