问题
I have a matlab function that returns results in a uitable.
There are 2 columns and lots of rows to the table: first column is "values" and second column is a "safety threshold/confidence interval" of sorts.
I'd like to format the output so that certain cells get painted red: those for which the "value" in column 1 exceeds the corresponding "safety threshold" in column 2.
Is there a way to do this using just Matlab?
PS: I am aware of the following page:

but it seems like a lot of tinkering to me, and I'm hoping that since that post was made, maybe Matlab has caught up and brought this functionality built in?

If you read the discussion carefully, you'll find out that UITABLE supports HTML content...
Here is an example:
X = rand(100,2);
%# convert matrix of numbers to cell array of strings (right aligned)
XX = reshape(strtrim(cellstr(num2str(X(:)))), size(X));
%# find cells matching condition
idx = ( X(:,1) > X(:,2) );
%# use HTML to style these cells
XX(idx,1) = strcat(...
'<html><span style="color: #FF0000; font-weight: bold;">', ...
XX(idx,1), ...
'</span></html>');
%# create table
f = figure;
h = uitable('Parent',f, 'Units','normalized', 'Position',[0.05 0.05 0.9 0.9]);
%# set table data
set(h, 'Data',XX)
