How to save uitable & uifigure into pdf file?

I am generating a table and graph using uitable and uifigure function, and I need to save the uitable and uifigure into pdf file. However, the pdf file was successfully generated but it's blank. Is there anyway to do that? My codes are as follow: ________________________________________________

fig = uifigure('Name','Numbers');
t = uitable(fig,'Data',[2,4,6,8;1,3,5,7]);
saveas(gcf,'Numbers','pdf')

fig = figure('Name','Numbers');
t = uitable(fig,'Data',[2,4,6,8;1,3,5,7]); 
saveas(gcf,'Numbers','pdf')

Apparantly there is some problem with uifigure while setting it as parent of uitable.

it works!!!! thanks!!!!!!!!!

NOTA BENE: In

fig = figure('Name','Numbers');
t = uitable(fig,'Data',[2,4,6,8;1,3,5,7]); 
saveas(gcf,'Numbers','pdf')

gcf does not necessarily return the same handle as fig -- even though it's highly likely it will, MATLAB instructions are not atomic and a selection of another figure could be made between the creation of fig and the execution of saveas. To be certain, use

saveas(fig,'Numbers','pdf')

Since R2021b, see exportapp which will include uicontrols; prior functions could not.

In the original, gcf doesn't return the handle of a uifigure but either an existing figure, or if one isn't already open, it creates a new one--either way, it will NOT be the handle of any uifigure.

I am trying exactly this right now, but the text in a UITable (which is a child of the UIFigure) is not showing in the PDF that is generated. Are children's contents not rendered when using exportapp?

[dpb]

fig = uifigure('Name','Numbers');
t = uitable(fig,'Data',[2,4,6,8;1,3,5,7]);
exportapp(fig,'Numbers.pdf')
winopen('Numbers.pdf')

produced a pdf file with the above content in it...would have to see specific code to see what may have gone wrong in your case.
