Description

Some changes to the docs based on our students' experience with the user guide.

• Add Export to Import/Export
• Remove SummarizeIf (not present to my knowledge in current version)

Testing

Did you add a unit test?

Thanks. There are some good ideas here. I haven't touched this project or the docs in awhile, but I see there's a docs-src directory and I assume based on its name that the changes would need to be made there instead.

I found the docs and moved them to a new contributing guide to make them easier to find. It looks like it is intended to have two copies of the docs, but you do indeed need to make changes to docs-src rather than docs. See https://github.com/jtablesaw/tablesaw/blob/master/CONTRIBUTING.md
