I would like to draw the kind of table (I don't know any proper name for this, so I cannot research for similar question) shown in the picture below:
I have absolutely no clue on how I can draw it. Do you know any package/simple way to draw it? If possible, what the macro should draw a vertical bar on each side, plus any number of smaller vertical lines inside the "table". The content of each part will always be in the form
$a \dots a$, with one symbol on each side and the space in between filled by dots (potentially more than 3 dots). One bracket below every part, on all its length (or slightly smaller for esthetic reason). No bracket above or on the sides.
This looks similar to a tabular environment but:
- How can I obtain vertical lines with different heights?
- How can I obtain the below brackets?
As you can guess, I cannot provide a MWE.
