making column visible - column shown without header

making column visible - column shown without header

Hi

Great Project, wonder if someone could tell me if the following is a problem with my implementation or a datatable issue. Have read a few forum posts with regards the colvis and responsive extension and am a bit confused if they can be used in the way shown here.

Debug: https://debug.datatables.net/izacar

Problem: when making a column visible - new table column data is shown without a header when width should dictate only a responsive (+) row be used

Example of this problem is available here:

https://ovits.com.au/dt_prob/dt_prob_orders.php

Using Bootstrap4

Have 10 Columns in Editor
Display 8 by default, if space available (two set with visible:false)

Issue occurs on desktop and mobile browsers

On Desktop - Windows 10 with Firefox 79 (with enough width for all 8 columns), when adding a 9th Column to table (colvis button):

  1. If enough space available for new visible column it works as expected added column with header https://ovits.com.au/dt_prob/when_enough_space.png

  2. If (screen space / window) is smaller than what is needed: a responsive row (+) is added to row but also a data column without a header https://ovits.com.au/dt_prob/problem.png

A page refresh resolves the visual problem when stateSave: true - complete is shown in the (+) only https://ovits.com.au/dt_prob/refresh_no_problem.png

Mobile (Apple - Safari - Portrait)

Three columns shown by default - Click Visibility -> Complete https://ovits.com.au/dt_prob/ios_dt_prob.png

Steps to recreate on desktop:

Open page
Resize width of page so Acknowledge disappears inside a (+)
Resize width of page slightly to reshow Acknowledge
Select Visibility -> Complete OR "Show All"
Complete column will appear on right without header as well as in a (+) row
Refresh page
Table should only show Complete column in responsive (+) row only

Steps to recreate on mobile:

Open page
Select Visibility -> Complete OR "Show All"
Complete Column will appear on right without header as well as in a (+) row
Refresh page
Table should only show Complete column in responsive (+) row only

Thanks in advance for any advice / help

Pete

    Hi,

    I'm seeing that as well. It does indeed look like a bug in our software somewhere. I'm not immediately sure where though!

    Could you load in the nightly version of Responsive on your page please?

    Thanks,
    Allan

    Hi Allan
    thank you very much for your response, have updated the page. apologies for this not being a fiddle, not sure if its relevant but i did try using fixed data and could not reproduce issue, so it seemed like it was ajax related, thought it would just be easier to strip a real page - would be happy to give you access to this if it would help
    thanks pete

    just fyi here is a fixed data (no ajax) example where it works fine (or it seems to):

    Thanks for updating the file!

    I've just made a small change to Responsive which I believe will fix this (it did when messing with variables on your site).

    The nightly will rebuild in about 5 minutes, so hopefully you'll be able to do a ctrl-f5 reload on your page soon to get the latest version of the file and it will "just work".

    Hey Allan
    You are a legend, thank you so much for this fix, really appreciate your effort, datatables is an outstanding project but the support is on a different level altogether.
    if you are ever in Aus let me know as I owe you a beer
