TableBuilder id_salt does not result in unique scroll areas

[jwhear]

Describe the bug
TableBuilder.id_salt does not result in unique table scroll areas.

To Reproduce

use eframe::egui;
use egui_extras::{Column, TableBuilder};

fn main() -> eframe::Result {
    let options = eframe::NativeOptions {
        viewport: egui::ViewportBuilder::default().with_inner_size([320.0, 240.0]),
        ..Default::default()
    };
    eframe::run_native("My egui App", options, Box::new(|_| Ok(Box::new(MyApp {}))))
}

struct MyApp {}

impl eframe::App for MyApp {
    fn update(&mut self, ctx: &egui::Context, _frame: &mut eframe::Frame) {
        egui::CentralPanel::default().show(ctx, |ui| {
            ui.horizontal(|ui| {
                let mut table = |salt| {
                    //ui.push_id(salt, |ui| {
                    TableBuilder::new(ui)
                        .id_salt(salt)
                        .column(Column::initial(60.0))
                        .vscroll(true)
                        .body(|body| {
                            body.rows(30.0, 100, |mut row| {
                                let index = row.index();
                                row.col(|ui| {
                                    ui.label(format!("{index}"));
                                });
                            });
                        })
                    //});
                };

                table("left");
                table("right");
            });
        });
    }
}

Despite setting different ID salts, a warning appears (reused scroll area id) and the tables scroll together.

Uncommenting the push_id call results in correct behavior.

Expected behavior
Using id_salt with distinct salts should result in independently scrolling tables.
