Description of problem:
When using dataTables.tailwindcss.js and if the table can be scrolled in x-direction, the issue of misalignment of the head is observed. If the view width is larger (no scrollbar is displayed), the header is aligned.
You can remove these two lines and see that the issue only happens when they are used.
<script src="https://cdn.datatables.net/2.1.8/js/dataTables.tailwindcss.js"></script>
<script src="https://cdn.tailwindcss.com"></script>
It seems that the padding of the header cell (thead.cell) is not taken into account.
After I comment out this part:
// Default class modification
$.extend( true, DataTable.ext.classes, {
container: "dt-container dt-tailwindcss",
search: {
input: "border placeholder-gray-500 ml-2 px-3 py-2 rounded-lg border-gray-200 focus:border-blue-500 focus:ring focus:ring-blue-500 focus:ring-opacity-50 dark:bg-gray-800 dark:border-gray-600 dark:focus:border-blue-500 dark:placeholder-gray-400"
},
length: {
select: "border px-3 py-2 rounded-lg border-gray-200 focus:border-blue-500 focus:ring focus:ring-blue-500 focus:ring-opacity-50 dark:bg-gray-800 dark:border-gray-600 dark:focus:border-blue-500"
},
processing: {
container: "dt-processing"
},
paging: {
active: 'font-semibold bg-gray-100 dark:bg-gray-700/75',
notActive: 'bg-white dark:bg-gray-800',
button: 'relative inline-flex justify-center items-center space-x-2 border px-4 py-2 -mr-px leading-6 hover:z-10 focus:z-10 active:z-10 border-gray-200 active:border-gray-200 active:shadow-none dark:border-gray-700 dark:active:border-gray-700',

last: 'rounded-r-lg',
enabled: 'text-gray-800 hover:text-gray-900 hover:border-gray-300 hover:shadow-sm focus:ring focus:ring-gray-300 focus:ring-opacity-25 dark:text-gray-300 dark:hover:border-gray-600 dark:hover:text-gray-200 dark:focus:ring-gray-600 dark:focus:ring-opacity-40',
notEnabled: 'text-gray-300 dark:text-gray-600'
},
table: 'dataTable min-w-full text-sm align-middle whitespace-nowrap',
thead: {
row: 'border-b border-gray-100 dark:border-gray-700/50',
cell: 'px-3 py-4 text-gray-900 bg-gray-100/75 font-semibold text-left dark:text-gray-50 dark:bg-gray-700/25'
},
tbody: {
row: 'even:bg-gray-50 dark:even:bg-gray-900/50',
cell: 'p-3'
},
tfoot: {
row: 'even:bg-gray-50 dark:even:bg-gray-900/50',
cell: 'p-3 text-left'
},
} );
More precisely, just commenting on this part will make the problem disappear:
thead: {
row: 'border-b border-gray-100 dark:border-gray-700/50',
cell: 'px-3 py-4 text-gray-900 bg-gray-100/75 font-semibold text-left dark:text-gray-50 dark:bg-gray-700/25'
},
tbody: {
row: 'even:bg-gray-50 dark:even:bg-gray-900/50',
cell: 'p-3'
},
I make a test to only remove the padding (px-3) from the header cell. The problem disappears!
thead: {
row: 'border-b border-gray-100 dark:border-gray-700/50',
cell: 'py-4 text-gray-900 bg-gray-100/75 font-semibold text-left dark:text-gray-50 dark:bg-gray-700/25'
},
tbody: {
row: 'even:bg-gray-50 dark:even:bg-gray-900/50',
cell: 'p-3'
},
Maybe we need to take the padding into account when calculating the column width?
(yeah. Calling columns.adjust() would also work)

Does it happen for you here: https://live.datatables.net/xunuceji/1/watch?html,js,output ?
I think your example might have been using an old cached version of the nightly (I need to modify its ttl!).
Allan
It still happens I'm afraid, BUT only in Chrome! wow!
I just open it in Firefox, and it is OK!
That's frustrating! What version of Chrome are you running? I've got 129 on a Linux host and the example appears to work okay. I'll try a Windows machine later on when I get to one.
Allan
The latest one:
Chrome is up to date
Version 129.0.6668.90 (Official Build) (64-bit)
Can someone help opening it (https://live.datatables.net/xunuceji/1/watch?html,js,output) to confirm this?

Misalignment issue in:
Chrome: Version 129.0.6668.90 (Official Build) (64-bit)
Edge: Version 129.0.2792.79 (Official build) (64-bit)
Arc: Based on Chromium version 129.0.6668.90 (Official Build) (64-bit)
It seems that all Chromium based browser has issue for me using Windows 10 64-bit
Firefox Version 131.0 (64-bit) works fine.
I see the issue with Chrome 129.0.6668.90 on a Mac.

Apologies, I forgot to try this at home last night. I've marked it so hopefully I remember tonight!
Thanks for checking and confirming as well Kevin!
I would be most unexpected if Chrome/Linux rendered something like this differently. It must be to do with how the OS is displaying / handling the scrollbars.
Allan
Just tried it on Win 10 with Chrome 129.0.6668.101 and unfortunately it still appears to work. There is something wrong with the footer though, and I can see that in Firefox as well.
Could you try this one: https://live.datatables.net/xunuceji/3/edit . It has a query parameter on the nightly file's URL to act as anti-cache. I'm wondering if there might be an old version in cache on an edge server somewhere.
Allan
It's slight but I still see the mis-alignment:
Sorting fixes the issue. Once fixed using the Run JS button doesn't cause the mis-alignment. The only way I can can recreate the mis-alignment is by reloading the page.
Kevin
Still misalignment here.
It will be more obvious when no scroll
I think it is not cache problem as I also experience this in my website using 2.1.8 but 2.1.6 works without issue!
