Column Names Tooltips for datatables

[Dario Strbenac]

Is there a more elegant approach to display a separate tooltip for each column name (such as a longer column name) than using eval and parse, as mentioned at http://stackoverflow.com/questions/31124122/r-shiny-mouseover-text-for-table-columns ?

eval(parse(text = ?)) is almost always a bad idea. I just completed my
answer on SO.
