Automatically wrap long lines in reaction tables.

[kalekundert]

For example, when making 16 plasmids at once, the primer list gets very long:

Reagent                                                                           Stock    Volume
─────────────────────────────────────────────────────────────────────────────────────────────────
water                                                                                     9.50 µL
o187,o166,o168,o168,o168,o172,o172,o172,o173,o174,o176,o171,o177,o179,o181,o183  100 µM   0.25 µL
o156,o167,o167,o169,o170,o167,o169,o170,o170,o175,o167,o167,o178,o180,o182,o184  100 µM   0.25 µL
─────────────────────────────────────────────────────────────────────────────────────────────────

tabulate() already supports newlines, so I would need to:

• Specify which column(s) should be wrapped.
• Figure out a wrapping width. Presumably this would be the same as the truncation width. In fact, maybe I can use the same argument.
• Figure out where to add the newlines. Note that the example above has no spaces, so I can't just use textwrap.wrap(). In the above case, it'd be nice to break on a comma, but I'm not sure if there's a general way to do that.

Regarding breaking on commas: I could change my scripts to use spaces when concatentating reagent names like that.

One problem is that tabulate() works out column widths after resolving newlines. This makes sense (columns widths depend how the lines break), but it means that this feature won't be trivial to implement.

[kalekundert]

An alternative solution (which ties in with #35) is to allow reaction tables to indicate which column(s) should be truncated. This would still mean some information is lost, but the most important information (i.e. the volumes) would not be.

I'm not planning to address this issue anymore, for two reasons:

• With the new Reactions framework, I am much less likely to get these kinds of long lines.
• I'm planning to transition to LaTeX output soon, and then this won't be a problem anymore.
