Hi

Googling showed me that the question has been asked 2 years ago, so I
repeat it just in case:

Any plans to implement true column hiding for org tables?


Concerning narrowing (poor man version of hiding)


| Name     | passport | Other |
|          | <2>      |       |
| John Doe |  1234567 |       |

In a org mode buffer (not here in a message buffer even with orgtbl-mode
enabled)

C-c C-C gives

| Name     | <2> | Other |
|          | <2> |       |
| John Doe | <2> |       |


The question is simple: how can a toggle narrowing?

thanks

What is true column hiding? What is the question you are referring to?

I don't understand your question.

Most of the spreadsheet application I know allow you 

    -  to mark a column 

    -  and to hide it (it is still there and can be displayed of course)

That question was asked for example in
https://www.reddit.com/r/emacs/comments/2blff3/is_it_possible_to_hide_some_columns_from_an_org

I now that I can hide regions in emacs but I am not sure about rectangles.

    > I don't understand your question.



    -  Well part one:

Original table


| Name | Passport | other |
|      |      <2> |       |
| Joe  |   123456 |       |
| John |   456789 |       |



    -  part two: narrow the second column


| Name | =>> | other |
|      | =>> |       |
| Joe  | =>> |       |
| John | ==> |       |


    -  part three missing: how can I recover the original table (something like
       widening)?????





The only solution I came up with is rather  cumbersome

(defun org-table-turn-narrowing-off ()
  (interactive)
  (setq org-table-do-narrow nil)
  (message "Now table narrowing is off!"))

(defun org-table-turn-narrowing-on ()
  (interactive)
  (setq org-table-do-narrow t)
  (message "Now table narrowing is on!"))

(defun org-table-toggle-narrowing ()
"Toggle function between New subject is in same thread or not."
  (interactive)
  (make-repeat-command 'org-table-toggle-narrowing
                      '(org-table-turn-narrowing-on
                        org-table-turn-narrowing-off)))

Turning narrowing of and run C-c C-c again.

I hope there are more comfortable solutions.

Not that I know of. How would you select a hidden column to unhide it?

This is a good idea for your use case.

> The question is simple: how can a toggle narrowing?

To view all columns at once you can temporarily "C-c SPC C-c C-c" on
<2> and double undo.

To view only one field at a time and optionally edit it you can use
"C-c `" with zero, one or -- the coolest -- two C-u prefixes:

    (info "(org) Built-in table editor")

    `C-c `     (`org-table-edit-field')'
      Edit the current field in a separate window.  This is useful for
      fields that are not fully visible (*note Column width and
      alignment::).  When called with a `C-u' prefix, just make the full
      field visible, so that it can be edited in place.  When called
      with two `C-u' prefixes, make the editor window follow the cursor
      through the table and always show the current field.  The follow
      mode exits automatically when the cursor leaves the table, or when
      you repeat this command with `C-u C-u C-c `'.

Similar as in LO/OO excel and friends, I would need to have
org-table-toggle-coordinate-overlays on
and so columns are indicated by $1, $2 etc
and hidden columns would correspond to missing numbers

|$1-+|$6

so $2, $3 $4 $5 are hidden

That is indeed cool thanks

I toyed with the idea, and came up with a proof-of-concept, attached to
this message. 

Basically, it defines two user-facing functions: `org-table-hide-column'
and `org-table-show-column'. Whenever the contents of an hidden column
is changed by the user, the column is shown automatically.

It is probably full of bugs, and I'm not sure it's really worth it, but
here we go. Note that the implementation uses overlays rather than text
properties, so hidden columns are not preserved upon closing and opening
a document.

Feedback welcome.

Regards,

Great thanks I will test this now, I presume this patch is against the
latest stable version?

No, it is against development version, aka "master" branch.

Ok I cloned that branch, applied your patch and run some tests, (using
GNU emacs 26)

Here are my impressions.


    -  (org-table-hide-column nil) works nicely! I can hide several columns: I
       start with the first, hide it,  move to the second hide etc

    -  however (org-table-hide-column 1) etc did not work as expected,
       the first column was hidden but when I called
       (org-table-hide-column 2) that column  was not hidden! Then I
       found out the culprit. I had the cursor on a different column. So
       (org-table-hide-column 1) seems to work best if the cursor is not
       on the table!

    -  would it be possible to hide various column on the fly. Either by
       marking them or running (org-table-hide-column 1 2 3) or
       something like this.

Thanks very much for this, I would it very useful and think it should be
included at some point in master.

I toyed a bit further with the idea, and re-designed the whole thing.

The new implementation provides a single user-facing function:
`org-table-toggle-column-visibility'. Here is its docstring:

    Shrink or expand current column in an Org table.

    When optional argument ARG is a string, use it as white space
    separated list of column ranges.  A column range can be one of
    the following patterns:

      N    column N only
      N-M  every column between N and M (both inclusive)
      N-   every column between N (inclusive) and the last column
      -M   every column between the first one and M (inclusive)
      -    every column

    When called with `C-u' prefix, ask for the range specification.

    When called with `C-u C-u' prefix, expand all columns.

In particular, when called with a prefix argument, it allows you to
type, e.g., "1-3 5 6-" and have columns 1, 2, 3, 5, 6 and onward shrunk
or expanded, according to their current state. I find it quite
efficient.

I imagine it can be useful when handling wide tables, but so can "<cX>"
cookies.

Anyway, feedback welcome.

Regards,

I just applied the patch and installed it and run a quick test. Great!
A huge improvement. I will test it during the day and report back if I
see something worth to mention.

Thanks again

good ideas.

i'd want it to be stored in the table, not in the user's head.

more radical ideas:

  - toggle: remove spc and | and use a minimal column -t or align.el type setup
  - edit: similar to c-c ' for babel blocks, but opens up a really
nice ses type spreadsheet

This is unrelated to column narrowing, isn't it?

spc and | waste space.  i am saying toggle minimal presentation of table.

for me, column narrowing is to preserve space.  a c-c ' for a nice ses
type spreadsheet might be a better truncation scheme for some.  for
example, you go to a cell and [formula and contents] shows in
minibuffer.  also intuitive imo.

so it's tangential.

never mind these ideas if they are too radical.

Actually, from an Model-View-Controller point of view, storing narrowing
cookies in the table is mixing Model and View. Narrowing a new column
requires to change the data, which is bad.

Furthermore, narrowing cookies influence export, so this is not
gratuitous at all.

IMO, dynamic narrowing makes much more sense than static one.

There is no space in shrunk columns. Such a column looks like this: |…|

True, there are still "|", but removing them would be ambiguous:

    | and so on…until |      

vs

   | and so on |…| until |

Expanded columns still have to be readable.

Since I don't know what is a "nice SES type spreadsheet", I cannot
comment on this. Do you mean that C-c ' should open the table as an SES
spreadsheet?

If so, converting the data would be easy, converting the formulas more
difficult.

How is this an example for the above idea? SES is a spreadsheet whereas
the above is about using minibuffer to display fields.

This can be implemented independently of columns narrowing so this is
orthogonal to the current patch.

I tested it quite a bit yesterday. There was only one problem concerning
pabbrev mode which scans the buffer periodically and this scanning did
widen the columns at some point. One can try this out by running
(pabbrev-scavenge-buffer) in an org buffer with columns being narrowed:
the columns will widen. But I am not sure whether this is a bug of your
implementation. I am happy with turning pabbrev mode off in org buffers
with large table where I need to narrow.


BTW what's about hiding rows? For very long tables (~100 and more rows)
hiding can be convenient. I do that by running hide-region (a third
package found in elpa). But maybe that feature could be included in org
mode as well?

Thanks

I could not reproduce it. Columns are automatically expanded whenever
contents change in a field (and change is not wrapped within
`org-table-with-shrunk-columns'). AFAICT, `pabbrev-scavenge-buffer' uses
`with-silent-modifications' so that shouldn't happen.

Hiding rows is a different beast. For example, it doesn't make sense to
have a feature to hide current row since Org rows are already
1 character high. So, we would only want to hide contiguous rows.

But then, the problem is that hlines may disappear and the formulas
could be more difficult to write (without using
`org-table-toggle-coordinate-overlays'). Perhaps we could only allow to
hide columns between 2 hlines. 

Do you have any idea about the interface of such functionality?
