Previously it would split the last column on the first separator value found
between the start of the column and the end of the row. Changing this to using
everything from the start of the column to the end of the string makes it behave
more similarly to the other columns, making it less surprising.
The table parsing/creation logic has changed from treating every line the same
to processing each line in context of the column header's placement. Previously,
lines on separate rows would go towards the same column as long as they were the
same index based on separator alone. Now, each item's index is based on vertical
alignment to the column header.
This may seem brittle, but it solves the problem of some tables operating with
empty cells that would cause remaining values to be paired with the wrong
column.
Based on kubernetes output (get pods, events), the new method has shown to have
much greater success rates for parsing.
New tests are added to test for additional cases that might be trickier to
handle with the new logic.
Old tests are updated where their expectations are no longer expected to hold true.
For instance: previously, lines would be treated separately, allowing any index
offset between columns on different rows, as long as they had the same row index
as decided by a separator. When this is no longer the case, some things need to
be adjusted.
The benefit of this is that coloring can be made atomic alongside token
stream forwarding.
I put the feature behind a flag so I can continue to iterate on it
without possibly regressing existing functionality. It's a lot of places
where the flags have to go, but I expect it to be a short-lived flag,
and the flags are fully contained in the parser.
Previously, we would build a command that looked something like this:
<ex_cmd> "$it" "&&" "<ex_cmd>" "$it"
So that the "&&" and "<ex_cmd>" would also be arguments to the command,
instead of a chained command. This commit builds up a command string
that can be passed to an external shell.
