Current behavior
Scrollable table headers are offset if table does not have enough rows to need a scrollbar.

Expected behavior
Headers and table columns should align correctly whether table has a scrollbar or not.

• PrimeNG version: 10.0.3

It looks like a fix for this long-standing problem was attempted in #9218, but that fix only seems to align the header correctly if the table has a scrollbar. Headers are offset if table has no scrollbar.

I have the same issue.

A workaround I did is

.p-datatable-scrollable-body {
  overflow-y: scroll;
}

But this is annoying...

This is fixed in 11.0.0-rc.1, will back port to LTS versions as well.

@cagataycivici not sure if there was a regression, or if this actually wasn't fixed, but the problem is still present with PrimeNg 11.2.0. https://stackblitz.com/edit/primeng-scroll-table-header-offset-bug-11-2

The fix seems to set: overflow-y: scroll. Does this mean that the design intent is to show scrollbar even when it is not needed? Generally we want to avoid showing scrollbars as much as possible.

It is also still present in LTS 10.0.8:

The issue is still present in Primeng 14.0.0 if there horizontal scrollbar. To reproduce shrink the preview box. https://stackblitz.com/edit/primeng-scroll-table-header-offset-bug-11-2-gowmsr?file=src%2Fapp%2Fapp.component.html
