Complete and reformat conditionals.rst truth table

[ghost]

Addresses #117

UPDATE: This PR was updated based on comments in the original issue asking that the table use don't care entries to collapse the table. Current version generates a table without images or emojis.

If you prefer it without the unicode chars I can revert that and put it back to X's.

It's hard to say how it'll look once published on your site, but the preview seems a little loud compared to the rest of the content:

UPDATED: After most recent commit the table is collapsed:

The build failed on both attempts. I've seen this problem before when using unicode characters when Latex is involved. Unless someone knows how to work around this (I tried in the past for my own work and was unsuccessful) I'll switch back to 1's and 0's

! Package ucs Error: Unknown Unicode character 10060 = U+274C,
3220(ucs)                possibly declared in uni-39.def.
3221(ucs)                Type H to see if it is available with options.
3222
3223See the ucs package documentation for explanation.
3224Type  H <return>  for immediate help.
3225 ...                                              

The table would look like this if it used 1=valid, 0=invalid, X=don't care:

This would probably require a legend

googling tells me that only some latex implementations, not all, support unicode character embedding. Generally you need to use a code instead of the literal character, like you would for embedding non-ascii chars in html.

Update: Latest commit removes the symbols and just uses 1, 0, and x for valid, invalid, and don't care.

HTML Output looks like this:

PDF Output looks like this:

I see that there are svg files for pass/fail used in this doc and elsewhere. They might be suitable for the table. I'll take one more pass at this with the images.

[ghost]

Ok, I give up. I tried with the svg's and they work fine for html but aren't liked by latex. Looks like if you want images in the truth table you probably need to write some python or know sphinx/resturctured text (which I don't). Otherwise, you can just accept the text based table for now.

For the record the svgs would look nice if you can solve the problem of Latex (as they match the example icons):

Here's how I did it (which might be unacceptable because it fixes the sizes of the images)

.. |fail| image:: ../_static/fail.svg
    :width: 20pt
    :height: 20pt

.. |pass| image:: ../_static/pass.svg
    :width: 20pt
    :height: 20pt

====== ====== ====== ============
if     then   else   whole schema
====== ====== ====== ============
|fail|        |fail| |fail|
|fail|        |pass| |pass|
|pass| |fail|        |fail|
|pass| |pass|        |pass|
====== ====== ====== ============

@mdboom , as one of the last people to merge PRs in this repo, are you able to take a look at this one? Is there anything others could do to help?

[jdesrosiers]

I was fixing another bug on the conditionals page and noticed the table wrong and fixed that as well. After merging today, I noticed this PR. I'm going to close this as fixed by #143. I used simple text for the symbols. If anyone wants to do something prettier, please open a new PR.

ghost is actually me. I had two accounts (one for work and one for personal). I deleted my work one and consolidated everything under personal. Glad to see this closed.
