Re: [BUG] hline references on left side of table formula

[lompik@voila.fr]

Hi,

I was interested to use hline references on the left side. However I found out that it
is not completely unsupported.
When the left side consist of:
* single cells references, it does not work
* ranged cells, it works for me (org 8.0.3)

The patch below tranforms the single cell references to ranged cells .

However it still does not work for references like @+ or @- I$1.. , which can be solve 
using references like @I+1#1.

Thanks,

However, fields like @-I or @+II
