JavaFX: How to disable ScrollBars in TableView

问题

I hope everyone is doing well.

I have a TableView in javafx and I would like the table behavior to truncate the image of the TableView when the parent pane resizes too small to display the data, instead of it becoming scrollable. To clarify, I just want the ScrollBars disabled or not visible, so they don't show up.

Below is my hierarchy in case that helps.

Things I've tried below

I read this post, but the answer just makes the cells resize to fit the width, instead of disabling the ScrollBar. I read the documentation on ScrollBar's here, but I couldn't find a setVisible() or setEnabled() property. I also read the TableView documentation here with no luck.

I searched the Javafx css guide here and found that there are the two policies below that can refer to a scroll pane.

-fx-hbar-policy:
-fx-vbar-policy:

But wrapping the TableView in a ScrollPane did not work as expected. It did not allow me to "fit-to-parent". I would like to refer to these properties, but in a TableView directly if that's possible. Any suggestions are greatly appreciated.

Thank you so much for your time.

Hiding the scroll bars completely, whether they're "supposed" to be displayed or not, can be achieved with the following CSS:

.table-view .scroll-bar * {
    -fx-min-width: 0;
    -fx-pref-width: 0;
    -fx-max-width: 0;

    -fx-min-height: 0;
    -fx-pref-height: 0;
    -fx-max-height: 0;
}

If you want to disable all scrolling then you can add an event filter to the TableView:

table.addEventFilter(ScrollEvent.ANY, Event::consume);

// or if you only want to disable horizontal scrolling
table.addEventfilter(ScrollEvent.ANY, event -> {
    if (event.getDeltaX() != 0) {
        event.consume();
    }
});

If you don't want the TableView to shrink when the parent gets too small, set the min size to use the pref size:

table.setMinSize(Region.USE_PREF_SIZE, Region.USE_PREF_SIZE);

If you don't want the TableView to grow beyond its pref size, do the same with the max size. You can also give an explicit pref size if you want.
