Ahhh - it nearly does!

But look at this:

 --8<---------------cut here---------------start------------->8--
         *Tempolauf*
        #+ATTR_HTML: 
style="margin-left:auto;margin-right:auto;text-align:center;"
 |  Z | Station          | Meter | Etappe |  Zeit |  Rnd. | Pace Rnd. | Pace |
 |----+------------------+-------+--------+-------+-------+-----------+------|
 --8<---------------cut here---------------end--------------->8--

Becomes:

 --8<---------------cut here---------------start------------->8--
<b>Tempolauf</b>
        style="margin-left:auto;margin-right:auto;text-align:center;"
</p><table border="0" cellspacing="0" cellpadding="6" rules="groups" 
frame="hsides">
 --8<---------------cut here---------------end--------------->8--
 

The `style...' part must be trimmed and go inside the `<table>' tag.






Also, in this test:

 --8<---------------cut here---------------start------------->8--
 
* Example

#+ATTR_HTML: I am removed from ASCII export
  | THead 1 | THead 2 |

  #+ATTR_HTML: I am _NOT_ removed from ASCII export
  | THead 1 | THead 2 |

#+CAPTION: removed
  #+ATTR_HTML: NOT removed
  | THead 1 | THead 2 |

  #+CAPTION: removed
#+ATTR_HTML: removed
  | THead 1 | THead 2 |
 --8<---------------cut here---------------end--------------->8--
 

the second last `#+CAPTION: removed' is NOT removed.
