When I open the following table in org, the characters from the first + symbol in +bar to the last + symbol on the next line are struck out, i.e. drawn with a line through the text.
#+STARTUP: showall * foo | C | D | | E | +bar | |---+------| I do not believe this is intended behavior for +strike-through+ text. The + symbol serves triple duty in org syntax as a an indicator for +stricken words+, a line drawing symbol in tables, and a #+keyword prefix. I see little reason to continue to support +strike-through+ text. Perhaps the simplest solution would be to deprecate stricken text and disable it by default, allowing for an option to turn it on for backward compatibility.
