Tables in groups act strange

[nickpas]

Hi all,

I tried to make a screen layout showing multiple tables next to each other (with scroll bars in case the window can not fit everything). To arrange them, I used groups (with horizontal=True).
The result seems however to act rather strange. Mainly horizontal scrolling seems to be broken: all table content outside the original view doesn't render. I made a small example with the elements I used in my real program (see below). If you resize till you get a horizontal scroll bar and then scroll, you should see the effect (I run on MacOS).
The text below the table (in the same group), also seems to influence the behaviour. (If you remove it, the scrolling & rendering acts differently.)
For some reason, the tables also partially render on top of each other.
From the documentation (and many searches) I could not determine if it is allowed to put tables in groups or not. Can anyone clarify if what I try should work or not?

import dearpygui.dearpygui as dpg

dpg.create_context()

with dpg.window(label="Tutorial",horizontal_scrollbar=True):
    with dpg.group(horizontal=True):
        with dpg.group():
            dpg.add_text("table 1")
            with dpg.table(header_row=False):

                for i in range(5):
                    dpg.add_table_column()

                for i in range(300):
                    with dpg.table_row():
                        for j in range(5):
                            dpg.add_text(f"T1 Row{i} Column{j}")
            dpg.add_text("under table 1")

        with dpg.group():
            dpg.add_text("table 2")
            with dpg.table(header_row=False):

                for i in range(5):
                    dpg.add_table_column()

                for i in range(310):
                    with dpg.table_row():
                        for j in range(5):
                            dpg.add_text(f"T2 Row{i} Column{j}")
            dpg.add_text("under table 2")

dpg.show_metrics()

dpg.create_viewport(title='Custom Title', width=800, height=600)
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()

Did you find a workaround? In my case it seems to be fine when setting a width for the group or table. However, the same happens for collapsing_header and tree_node where you can't set a width...

Hi, no I didn't find anything at the time and the whole program got a bit to the background.

I did a quick test and adding a width does indeed seem to fix the issue at first sight. I'll need to start using the program again to test further. Thx!

I opened #2440

@nickpas please see my comments in #2440.

Thx, I also got the example code working by putting a table in a table. The fix/workaround above with width requires however less changes to the real code from my program and seems to work at first sight. When it would turn out to still have issues, I will check the solution with tables further. Thx!
