Issues with colspan (.txt output) and shading (.html, .pdf outputs) when trying to convert a figure to a table

[lbartholomew-rpc]

Issues with colspan (.txt output) and shading (.html, .pdf outputs) when trying to convert a figure to a table (Table 1 in the "-with-Table1" files listed below).

The "colspan" entries had several undesirable carriage returns each in the .txt output (the "BIFT indices for Packets with SI=0" and "BIFT indices for BitString/Packet with SI=1" rows).

Please see

https://www.rfc-editor.org/v3test/draft-ietf-bier-te-arch-13-with-Table1.pdf

The shading in the 4th row in the .html and .pdf outputs was off, but no carriage-return issue for the colspan entries.

To see what the correct layout should be, please see Figure 4 in

Seems to be another example of the colspan issue. Attempting to use <table> to create Table 5 in this document: https://www.ietf.org/id/draft-irtf-nmrg-ibn-intent-classification-08.txt
In the text output, see the 5 right-most columns --<th> is being forced into one column even though it has colspan set greater than 1 (e.g., <th colspan="6">Intent Scope</th>).

#886 is a fix for the table colspan issue in text format.
Generated table for the above example is as follows:

   +===========+=============+=================+=====+=====+=====+=====+
   |Intent User| Intent Type |Intent           |DCN  |DCN  |ABS  |L-C  |

Hi, kesara. I don't see the fix implemented yet. Which version of xml2rfc will implement it? We have 3.15.0. Thanks!

[kesara]

@lbartholomew-rpc, My bad. There are two issues separate issues.
3.15.0 should have the fix for the table column issue in #833 (comment)
Can you confirm?
HTML shading issue is not fixed yet.
I think the examples in #833 (comment) are stale now. (EDIT: They are not stale.)

[lbartholomew-rpc]

Hi, Kesara. Thanks for clarifying. I tested today with draft-ietf-bier-te-arch-13-with-Table1 and didn't see a change. Text output of draft-ietf-bier-te-arch-13-with-Table1-10Oct2022_Issue-833.txt is attached below. Guessing that you're talking about the "colspan-table-example" part of the ticket instead? If yes, I'll ask Alice Russo to verify that one. Thank you again! Lynne

@lbartholomew-rpc, looks like GitHub doesn't post attachments from email replies.
Can you attach the draft-ietf-bier-te-arch-13-with-Table1-10Oct2022_Issue-833.txt to this issue?

Yes.

Hi, @kesara. Here's that snapshot from earlier today (same issue as the one I'd reported initially). Thank you, & sorry for trying the email route.

Re: 3.15.0 should have the fix for the table column issue in #833 (comment)
Can you confirm?

Confirmed (re: <th colspan="6">Intent Scope</th>).

However, as @lbartholomew-rpc pointed out in #833 (comment), the original input file (draft-ietf-bier-te-arch-13-with-Table1.xml) still has the issue in the TXT output where each word of this <td> appears on its own line:
<td colspan="3" align="center">BIFT indices for Packets with SI=0</td> (and the same issue when align="left")

I'm closing this ticket as it's not possible to find a good solution for the shading issue with colspan in CSS. Any additional elements that can be introduced to fix a simple colspan shading will fail with complex cases where there are multiple colspan values in a single row.

Other issues in this ticket are solved.
