Other people and other projects have faced same issues as you are facing in Org mode, and have resolved it. To understand anything one cannot just read simple reference, but better understand the surrounding meanings, the context. Org tables are nothing harder or simpler than tables in other lightweight markup languages. What appears "unreadable" to you is readable to other person. In fact, there is no single char in the extreme example of Asciidoc table below that you can't read. The meaning of "unreadable" is most probably "not understandable". That is why I said, one has to inspect the context and look for definitions. [cols="e,m,^,>s",width="25%"] |=== |1 >s|2 |3 |4 ^|5 2.2+^.^|6 .3+<.>m|7 ^|8 |9 2+>|10nnp |=== In fact, looking into functionality of other lightweigh markup languages may only be helpful for Org development. For [cols="e,m,^p,>s",width="25%"] look here: https://docs.asciidoctor.org/asciidoc/latest/tables/format-column-content/ Thus `e' before first comma, means emphasized (I guess) and in fact on the original demonstration one can see that first column is emphasized. The fact that one may "describe" column's font style in Asciidoc(tor) could be adopted as well in Org mode. `m' after first comma says that text of that column shall be in monospaced font, which I find very useful for table columns. `^' signifies centered column in `[cols="e,m,^,>s",width="25%"]' and `>s' means right centered, bold column; `width=25%' tells about table width. I would like it if Org mode could provide such functionality for tables, to specify various attributes for columns. It does provide, though I am not sure if it can provide so many. And in that extreme example then we have following lines: |=== for begin of the table |1 >s|2 |3 |4 the second `|' has attribute `>s' or complete `>s|' which specifically formats number "2" to be bold and right centered. ^|5 2.2+^.^|6 .3+<.>m|7 It is good to read about span factor: https://docs.asciidoctor.org/asciidoc/latest/tables/span-cells/ 2.2+^.^|6 -- talks about spanning 2 columns, two rows and its alignment. while .3+<.>m|7 talks about spanning 3 rows, that is where number 7 comes. |=== for end of the table It is surely good to try to make visual tables with merged cells as general Org functionality. It is also very useful to look how other people implement various functionalities and try to see if such could be useful in Org as well. But when you don't have the functionality yet, due to the Babel and inclusion of other files, one may achieve the final result by including HTML directly, or by using external tools. Org is integrator of almost anything. Babel and integration of, to the Org external tools, allows user to include almost any value or results from outside the file. I do agree that it is "hard" to understand at once what it is, but it is a solution for reason that Org allows external tools' values to be included in the Org file. In this case it is the HTML output from Asciidoctor. This elaboration is for opening the mind of Org user, it is to understand that extensibility, due to Babel and inclusion of any external tools has no limits at any point of time. One need not wait for that feature X to be implemented in Org, while there is plenty of available options to reach the purpose of feature X. #+BEGIN_SRC shell :results raw echo " [cols=\"e,m,^,>s\",width=\"25%\"] |=== |1 >s|2 |3 |4 ^|5 2.2+^.^|6 .3+<.>m|7 ^|8 |9 2+>|10nnp |=== " | asciidoctor -e -o - - #+END_SRC #+RESULTS: <table class="tableblock frame-all grid-all" style="width: 25%;"> <colgroup> <col style="width: 25%;"> <col style="width: 25%;"> <col style="width: 25%;"> <col style="width: 25%;"> </colgroup> <tbody> <tr> <td class="tableblock halign-left valign-top"><p class="tableblock"><em>1</em></p></td> <td class="tableblock halign-right valign-top"><p class="tableblock"><strong>2</strong></p></td> <td class="tableblock halign-center valign-top"><p class="tableblock">3</p></td> <td class="tableblock halign-right valign-top"><p class="tableblock"><strong>4</strong></p></td> </tr> <tr> <td class="tableblock halign-center valign-top"><p class="tableblock"><em>5</em></p></td> <td class="tableblock halign-center valign-middle" colspan="2" rowspan="2"><p class="tableblock"><code>6</code></p></td> <td class="tableblock halign-left valign-bottom" rowspan="3"><p class="tableblock"><code>7</code></p></td> </tr> <tr> <td class="tableblock halign-center valign-top"><p class="tableblock"><em>8</em></p></td> </tr> <tr> <td class="tableblock halign-left valign-top"><p class="tableblock"><em>9</em></p></td> <td class="tableblock halign-right valign-top" colspan="2"><p class="tableblock"><code>10nnp</code></p></td> </tr> </tbody> </table> -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns In support of Richard M.

We do not support some features ASCIIDOC supports. ASCIIDOC does not support spreadsheet features of Org tables. That's why we need context.

But we have different proposals in the previous emails. Compared to the existing proposals, this looks unreadable. (which does not mean that it is worse - maybe ASCIIDOC has more flexibility; but less readable compared to other proposals for sure). > In fact, looking into functionality of other lightweigh markup > languages may only be helpful for Org development. > > For [cols="e,m,^p,>s",width="25%"] look here: > https://docs.asciidoctor.org/asciidoc/latest/tables/format-column-content/ > Thus `e' before first comma, means emphasized (I guess) and in fact on > the original demonstration one can see that first column is > emphasized. > > The fact that one may "describe" column's font style in Asciidoc(tor) could > be adopted as well in Org mode. Thanks for the link! This specific link is out of scope of this discussion (I do not think that we need to specify formatting for the whole column), but another link nearby looks more useful: https://docs.asciidoctor.org/asciidoc/latest/tables/span-cells/ > I would like it if Org mode could provide such functionality for > tables, to specify various attributes for columns.

However those who are brave enough to add cells spanning columns and rows may take some inspiration from reStructuredText, in particular horizontal lines marked by "+===+===+" https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#tables > Grid tables are described with a visual grid made up of the characters "-", "=", "|", and "+". The hyphen ("-") is used for horizontal lines (row separators). The equals sign ("=") may be used to separate optional header rows from the table body (not supported by the Emacs table mode). The vertical bar ("|") is used for vertical lines (column separators). The plus sign ("+") is used for intersections of horizontal and vertical lines. Example: > > +------------------------+------------+----------+----------+ > | Header row, column 1 | Header 2 | Header 3 | Header 4 | > | (header rows optional) | | | | > +========================+============+==========+==========+ > | body row 1, column 1 | column 2 | column 3 | column 4 | > +------------------------+------------+----------+----------+ > | body row 2 | Cells may span columns. | > +------------------------+------------+---------------------+ > | body row 3 | Cells may | - Table cells | > +------------------------+ span rows. | - contain | > | body row 4 | | - body elements. | > +------------------------+------------+---------------------+ RST tables have a feature making hard to implement autoalignment. If come cell have "|" with offset in respect to lines above and below then it is a regular character. Besides "grid" tables there are "simple" tables without vertical lines. Perhaps it better to implement new table features as src blocks for some new language and a dedicated Emacs mode. In the case of success such proof of concept may be merged into Org core. My impression is that Org tables quickly become hardly maintainable when their complexity is above some quite low threshold. E.g. automatic recalculation works only for first #+tblfm: line. It requires some efforts to figure out association of particular formula with cell spans. Merge cells add more complexity to formula ranges.

Uwe's proposal is supporting table.el more fully, but it will be incompatible (if taken as is) with the current Org table syntax. We can learn from the design, but cannot just blindly re-use it. > Besides "grid" tables there are "simple" tables without vertical lines. That's similar to the ASCIIDoctor tables as I read it in the link.

In the case of success such > proof of concept may be merged into Org core. That's what our table.el integration does. But it is not enough. Some features are only present in native Org tables and some features are only present in table.el tables. We will end up needing to extend either of the table syntaxes to obtain full Org table functionality. Then, it is better to extend native Org tables rather than replacing the existing table syntax with third party. > My impression is that Org tables quickly become hardly maintainable when > their complexity is above some quite low threshold. E.g. automatic > recalculation works only for first #+tblfm: line. It requires some > efforts to figure out association of particular formula with cell spans. I'd say that the problem is mostly with org-table.el which heavily relies on direct regexp matching. If we generalize things using parser, it should become easier to maintain even with merge cells. > Merge cells add more complexity to formula ranges.

Either way, it is a good idea to refactor org-table.el -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
