tables, comment in one line, export to html

tables, comment in one line, export to html

[Uwe Brauer]

Hello

I would like to have a table entry in which the last colum contains
comments which I don't want to export to html.

Like this

| Joe Smith      |  7 | 25 |  5 |    |  37 |       | #+begin_comment from group B B #+end_comment |

But this does not work. So how can I achieve it?

thanks

Thanks but this is supposed to work in a org mode buffer? Does not work
for me. Also I wanted to export the whole file not just a part of it in
the file. It seems that you are in a HTML buffer and use orgtbl radio
tables?

That I do in latex files but not in HTML files, they are just for me too
ugly to edit them directly.

Correction to my reply: it works, but it generates html code which I
have then to insert into a HTML file. I prefer directly to import the
whole org file. Can that be achieved?

I have the same need now and just hacked something simple together to
export

    | / | /  |    | <r> |

    | / | <r> | /  |    |

    | / | /  | /  | <r> | /  | /  | /  |
    |   | 1n | 2n |  3y | 4n | 5n | 6n |

    | / | <r> | <l> | <r> | <l> | <r> | <l> |
    | / |   / | /   |   / |     |   / | /   |
    |   |  1n | 2n  |  3n | 4y  |  5n | 6n  |

    # Same result with a less useful notation:
    | / | <r> | <l> | <r> | <l> | <r> | <l> |
    | / |   / | /   |     |     |   / | /   |
    | / |     | /   |   / |     |     |     |
    |   |  1n | 2n  |  3n | 4y  |  5n | 6n  |

    # Deletion must not get trapped with this:
    | / | <r> | <l> | <r> | <l> | <r> | <l> |
    | / |     |     |     |     |     |     |

    |   |  1y | 2y  |  3y | 4y  |  5y | 6y  |

as e. g. ASCII to

    :  2y  3y
    :
    :  1y  3y

    :  1y  2y
    :

    :  4y
    :
    :   /  /    /

Great!! thanks, I just tested it. So all columns having a / header are
ignored, at least for html and latex export. This is really great.
Thanks again. I'd say that code should be somehow included in mainstream
orgmode, if you don't mind?

Second the suggestion to make | / | columns ignored for export in 
mainstream orgmode.

It sounds good, as long as it is clear this markers is for export
consumption only, and has no special effect when using the spreadsheet.

I suggest to use # or <#> instead of / so as to refer to "comment" (but
still use / as the marker for the first column).

The removal could be done in a function like
`org-export--delete-commented-rows' (see `org-export--delete-comments'
in "ox.el").

This would also require documenting it in the manual and providing
tests.

Does anyone feel like doing that?

# in non-first columns to mean noexport of the column has the
disadvantage of possible confusion with # in the first column where it
means special effect for recalculation when using the spreadsheet. As
I understand your first paragraph you want to avoid such confusion.

/ in non-first columns to mean noexport of the column as I did before
has the disadvantage of possible confusion with / in the first column
where it means noexport of the row.

<#> I find a bit too near to <5>, <, > or <>.

% or ; used for comments in LaTeX or Emacs Lisp I would find a good
space saving single character alternative. Why not % as this would not
be the first time that Org borrowed some syntax elements from LaTeX?
The glyph has also similarities to / that has a similar meaning.

And just to mention if someone wants to start: The non-greediness I
did before is not necessary and could be omitted for better
readability:
old: "^[ \t]*| +/ +|\\(.*?|\\)?? +\\(/\\) +|"
new: "^[ \t]*| +/ +|\\(.*|\\)? +\\(%\\) +|"

And a change note.

I don't think there is a possible confusion if the manual makes it
clear.

> <#> I find a bit too near to <5>, <, > or <>.

That was exactly the point, since those all apply to columns, unlike to
rows special markers. IOW, so far, columns syntax systematically uses <
or > (or both).

Org comment syntax is related to #, not % or ;. I'd rather have similar
things look similar.

To have similar things look similar and make it clear in the manual I
suggest to change the long existing

  ~/~
     Do not export this line.  Useful for lines that contain the
     narrowing `<N>' markers or column group markers.

  Finally, just to whet your appetite [...]

to

  ~/~
     Do not export this row or column.  In the first column ~/~ means
     do not export this row which is useful for rows that contain the
     narrowing ~<N>~ markers, column group markers or markers to not
     export a column.  In all other columns ~/~ means do not export
     this column if also the first column is marked with ~/~.  When
     the first column should not be exported move its content other
     than markers into an other column.

  When more than one marker is needed in a column put each in an own
  row with ~/~ in the first column.

  Finally, just to wet your appetite [...]

You are talking about section "3.5 The spreadsheet". I don't think this
feature is directly related to spreadsheet capabilities.

Actually, / in first column is described earlier in the manual, in "3.3
Column groups". Besides, there is a similar feature described in "3.2
Column width and alignment", about lines containing only alignment
cookies:

     Lines which only contain these formatting cookies will be removed
  automatically when exporting the document.

IMO, a better change would be to merge 3.2 and 3.3 as "Column
operations" or some such, and add "<#>" as a way to ignore columns upon
exporting. This way, everything related to columns is packed in the same
subsection, and every column markup uses < or >. Moreover, there is no
possible confusion with # markup from spreadsheet.

WDYT?

Another advantage about this is that there is no need for "/" in the
first column, much like alignments cookies. It makes it simpler to
ignore the first column.

Hi Nicolas

I agree, together all the below makes sense. Some comments added.

<#> will have to be considered for removal of the line too.

<#> will have to be fontified like <5> as org-formula (name and
description of the face are not precise) wich is the easiest part of
the change. Shouldn't < and > in a table be fontified too?

Yes, it is really the same as alignment/width cookies. BTW, it should be
possible to merge them together. E.g., one could write <r10#> for
a right aligned 10 characters large column not meant to be exported.

This probably requires some slight changes in org-table.el.

They should, as long as the first field is "/", unlike to
alignment/width cookies. I wouldn't bother too much though, since
fontification needs to be rewritten using the parser, once the latter
get a more robust cache, that is.

Cool, thanks very much I tried out

| name  | result | @@html:<!-- Comment group B B -->@@ 
| Smith |     10 | @@html:<!-- from group B B -->@@    

Which does almost all I want, it inserts an empty third column, but I

Anyhow this solution is sufficient for me, but if you know how to get
rid of that third column, I would be even more grateful! Thanks again

Without real hackery, not unless you want the comment construct to be
part of the previous column in org?  I.e. move the | before the @@ to
the end of the line.
