Description

When using print-table to print an ASCII table to stdout, the table display breaks if any of the values is a string with any new lines in it. For example:

user=> (print-table [{:a "test" :b "test\ntest2"}])

|   :a |         :b |
|------+------------|
| test | test
test2 |
nil

I would expect the output to look something like this:

user=> (print-table [{:a "test" :b "test\ntest2"}])

|   :a |         :b |
|------+------------|
| test | test       +
|      | test2      |
nil

The + symbol on the right border means that the row continues over multiple lines. This is similar to how the PostgreSQL psql tool displays table with multi-line rows:

user=# select 'test' col1, E'test\ntest2\ntest3' col2;
 col1 | col2  
------+-------
 test | test +
      | test2+
      | test3
(1 row)

I have no direct knowledge of this, but my guess would be that the Clojure team would consider this an enhancement request rather than a defect.

You are likely to get what you want faster either by writing your own version of print-table that works as you wish, or see whether these projects already behave as desired, or the authors are willing to enhance them: https://github.com/cldwalker/table or https://github.com/joegallo/doric

JIRA destroyed my formatting, and looks like I can't edit it to fix it. Here is what I meant to say:
