Is it useful to display the Filter Button if filter-field is set to hide?
I suggest to modify that part to

			<?php if ($this->params->get('filter_field') !== 'hide') : ?>
				<div class="com-content-category__filter-submit control-group hidden-xs-up float-right">
					<div class="controls">
						<button type="submit" name="filter_submit" class="btn btn-primary"><?php echo Text::_('COM_CONTENT_FORM_FILTER_SUBMIT'); ?></button>
					</div>
				</div>
			<?php endif; ?>

Also, for a11y, the table is missing something like

<caption id="captionTable" class="sr-only">
					<?php echo Text::_('COM_CONTENT_ARTICLES_TABLE_CAPTION'); ?>,
				</caption>

@infograf768
I don't know if it is useful to display the Filter Button if filter-field is set to hide?
I haven't looked into the functionality of the rendered fields nor buttons. This is not the scope of this PR.

Table Caption out of scope of this PR too... created new pr for it. #30763

[infograf768]

I should have been more precise:
The Filter button IS useless when filter-field is set to hide...

[hans2103]

@infograf768 adjusted PR.
Actually you are saying that a PR was needed anyway to solve the display of the button? Not only to fix alignment

In a separate PR, filters section shouldn't be hidden when no items.
