Theme Olivero : no table zebra

The patch 3332049-1.patch has a little space problem:
s/&:nth-child(even){/&:nth-child(even) {/
With Drupal 9.5.8 the patch does not apply. With Drupal 10.0.x-dev the patch applied cleanly. But the table has no zebra. Since the tr elements in the table have no even/odd classes. If now in the Olivero theme the Claro table.html.twig file is used, then the table has zebra. A suitable table.html.twig file seems missing for the theme Olivero. Yes, Screenshot 2023-04-28 at 8.37.03 PM.png is what is expected.

@ Santosh_Verma I can't get the same result than you.

In my case, the page theme is Olivero. And the html table in this page is built through an html.twig file. On a Drupal 10.1.0 installation.
0) Apply your patch: 3332049-8.patch: OK: applied cleanly.
1) With the original Olivero theme the table html look like,

<table data-striping="1" class="dated">
	<thead>...</thead>
	<tbody>
		<tr data-info="paragraph/21294" id="paragraph/21294">...</tr>
		<tr data-info="paragraph/21286" id="paragraph/21286">...</tr>
		<tr data-info="paragraph/21287" id="paragraph/21287">...</tr>
		...

Visually: PB: table is not zebra. And there is no table.html.twig in the core/themes/olivero/templates/.
2) I alter the Olivero theme, by coping the table.html.twig file from Claro theme in core/themes/olivero/templates/dataset/.
Then (drush cr needed) the table html look like,

<table data-striping="1" class="dated">
	<thead>...</thead>
	<tbody>
		<tr data-info="paragraph/21294" id="paragraph/21294" class="odd">...</tr>
		<tr data-info="paragraph/21286" id="paragraph/21286" class="even">...</tr>
		<tr data-info="paragraph/21287" id="paragraph/21287" class="odd">...</tr>
		...

Visually: OK: table is zebra.

Fine @Santosh_Verma! Zebra gets in the table without table.html.twig file. Patch 3332049-13 applied cleanly.
Few remarks,
- The final/bottom horizontal line is missing in the table.
- In my case, better without,
padding-block: var(--sp1);: row less height, table more compact.
vertical-align: top;: no horizontal alignment problem in rows.
The full corresponding rule,

:is(.forum table, .text-content table, .views-table, .draggable-table, table) td, :is(.forum table, .text-content table, .views-table, .draggable-table, table) th {
	/* padding-block: var(--sp1); */
	padding-inline-start: 0;
	padding-inline-end: var(--sp1);
	/* vertical-align: top; */
}

@Kaustab_Roy, patch 3332049-17 applied cleanly, and makes what was missing. Only one little objection: the final line now exists, but its color if different from the first one. After a look to the patch and the page style, what about rather?,

 :is(.forum table, .text-content table, .views-table, .draggable-table, table) tr:last-child td {
-  border-block-end: 0;
+  border-block-end: 2px solid var(--color--primary-50);
 }

and,

     &:last-child {
       & td {
-        border-block-end: 0;
+        border-block-end: 2px solid var(--color--primary-50);
       }
     }

The file structure would be more the same. Nothing else in view.

If we can avoid to create a subtheme and only use the default Drupal theme it would be much better!

@Santosh_Verma, I suggested to use a table.html.twig from an other theme for Olivero, since in the old Bartik theme it was made this way, and some other themes have it. But not sure it is the good solution for Olivero. Yes, same folder for me, for the file table.html.twig in Olivero. We use this to mimic the old system. I enjoy your solution: using css nth-child(even)/nth-child(2n) instead of a twig. Only verified for our particular case. But no problems seen on our site. It is believable that problems occur with yours solutions or my suggestions in some cases. Is it possible to avoid this cases? May be reducing the ambitions of the patch. Seems important: our table does not come from a view: it is a table of paragraphs gets from modules reference_table_formatter and paragraph through a field of type entity_reference_revision. Basic for the style configuration. Surely, no enough images from our part, and so not easy to see how look like the problem. Here some images (from different places):
