Table not expanded as I expect upon <TAB>

Table not expanded as I expect upon <TAB>

[Alain.Cochard]

Maybe it is normal, but if I put the cursor anywhere in the 1st line
(say) of this table

||---+---|
|| x | x |

and press <TAB>, it becomes

|   | ---+--- |   |
|   | x       | x |

which is not what I would expect.


By contrast, if <TAB> on this one

|---|+---|
| x || x |

it becomes 

|---+---+---|
| x |   | x |

Further, by doing M-<LEFT> on the 2nd column, it becomes

|---+---+---|
|   | x | x |

and using <TAB> then does not change the table, which is the result I
would have expected to start with.

This is expected.
Only |- at the beginning of the line is seen by Org as horizontal rule.
||-... is an empty cell || followed by a cell |-...|.

See 3.1 Built-in Table Editor section of Org manual.

Yeah... I should have figured it out by myself.  Thanks a lot for your
time. 

But this got me thinking: I wonder if there is a reasonable/meaningful
use of <TAB> either in my above example (with one '|' on the left of
each row) or after inserting a single '|' on the top left position of
the following table

|---+---|
| x | x |

which gives

|   | ---+--- |
| x | x       |

At 1st sight, it does not seem so to me (in particular, LaTeX export
does not turn '---+---' into an horizontal rule for the 2
corresponding columns).  So then one could imagine that '|<TAB>' at
the beginning of a line starting by '|-' would be interpreted just as
'|-<TAB>'.  (Not a dramatic improvement, I admit :-)

Sorry, but I do not fully understand what you are referring to.
