Make it easier to parse tparse's summary table by
using null rune as table's borders, columns, and
rows' separators.

Question. By "parse" do you mean general look and feel of the output?

Or, would it be useful it tparse outputted the table in JSON format to be further consumed by tools like jq ?

---

Also, should the test table also output the data in the same manner?

I meant parseable with basic UNIX tools pipelines (i.e. made of cut, tr, etc).

Or, would it be useful it tparse outputted the table in JSON format to be further consumed by tools like jq ?

I suppose that that is already doable by directly parsing go test -json's output.

Also, should the test table also output the data in the same manner?

Totally, yes. I've made another commit, which should apply the same style to the tests table too 👍

Gotcha. Looks good to me. Thanks for the PR.

Here is what the output looks like now.
