It's one of the old legacy reports that will not likely be updated. Hopefully, at some point, it will be replaced by one that uses the new reporting engine and hence will have export functionality.
Until then, here's a workaround. You can select the whole thing (Cmd-A), copy (Cmd-C) and then paste into an Excel or Numbers spreadsheet. It will require a bit of reformatting, but at least it's something.

BTW, the columnar-type report is the basis for MANY other reports, as described in detail in this post a little lower; only the selection and formatting criteria are different.

Loren, all the reports you can generate via "New Report" -- the new reporting engine that continues to be developed -- allow exporting. So you can currently create and export a New Report > Transaction Report or New Report > Summary Report. Currently, the Net Worth Over Time report hasn't been created in the new report engine, and the old report style didn't allow exporting. This will hopefully be rectified as they move to replace the old reports with the new reports engine.
