phpMyAdmin supports table comments. These can be viewed in table pages, or in a schema's structure page, but only as tooltips.
I would like to directly see comments in schema structure pages. Considering that encoding and loss have columns by default, I think a truncated version of comments is as relevant and can be added by default, but if not, an option could do.
This applies to 4.4.6.
Sorry... I also forgot to mention that multiple table comments can be seen directly using the Print version (at the bottom), but this has disadvantages.
Note that the table comments are also shown in table Structure, not as a tooltip but in the header, next to the table name.
Where do you suggest to show table comments in database Structure?
Yes, that is what I was trying to say.
I am not sure we understand, I suggest to show table comments in schema Structure, as a column. If you were asking the position this column should have, I suppose it should be towards the end, since that column could be wide and low importance (surely after name and Actions), but I have no strong opinion on the precise position. I would place it after Lines, but it could be anywhere after.
I notice that Action is very large. Hiding the labels would be less clear, but a lot more compact.
