I am working on an app that ultimately produces 4 separate tables, each containing 4 columns of data. For simplicity, I am only including a single example, as I would think the process should be identical for all 4 tables, aside from the name of each table. All of the tables currently only show 4 decimal places. I would like to show more than this. I tried putting the following code in my startup function:
function startupFcn(app)
clc
close all
app.UITable.ColumnFormat = {'long','long','long','long'}; %4x 'long' - 1 for each column?
This does not seem to work, as all of the tables still only display 4 decimal places. Any help would much appreciated. Thank you.

Maybe some code is modifying the uitable after the startupFcn executes, because the code you've shown should work.
Here it is working with uitables in figures (since uifigures can't be created in the forum environment):
data = rand(3,4);
n_col = size(data,2);
f_args = {'Position',[10 10 840 100]};
t_args = {'Units','normalized','Position',[0 0 1 1], ...
'ColumnWidth',repmat({200},1,n_col),'Data',data};
% a table with default ColumnFormat
f = figure(f_args{:});
t = uitable(f,t_args{:});
% another table, identical to the first, except with ColumnFormat 'long'
f = figure(f_args{:});
t = uitable(f,t_args{:});
t.ColumnFormat = repmat({'long'},1,n_col);
I have also confirmed that it works with uifigures in R2022a.
