Row with padding selection background color table

I'm having troubles with adding my selection colour of my table to my padding area.
As you can see it does not stretch to the padding:

I added padding to my row like this:

.ia_table__body__row{
    border-bottom: 1px solid var(--color-row-border-bottom);
	padding: 0px 15px;
}

And my color for the selection background:

.ia_tableComponent__selection {
    background-color: rgba(12, 123, 179, 0.25); 
}

Anyone knows how to 'stretch' the my colour for the selection onto the padding?

Hello Corne_de_Jonge

I'm not sure if its possible to manipulate just the selection style, it seems like the selection style gets applied along with the row styling. You may be able to use the developer tools of your web browser to try and find the selection style that would need to be manipulated and add those changes to your themes.css file, here's a screenshot of those developer tools:
