MATLAB: Display table with numbers and text as uitable

uitable

If I have a simple matlab table, with some columns containing numbers(double) and other columns contain text(cell), how can I display it as uitable? E.g. the matlab table may read like:

Names Ages

John 12

Mike 10

Peter 15

Try this:

handles.uitable1.Data = table2cell(t);

where t is your table, and the uitable is a GUIDE control. If you're not using GUIDE, then just use

uitableHandle.Data = table2cell(t);

Use GUIDE, or uitable().

MATLAB: Existing table, populate a column with string (receiving errors)

You are close, but you are trying to assign a character vector to a double variable (NaN = not a number). You can see that if you run the command summary(mytable).

You also do not need to put the text into a cell if you use the string data type.

See if you can get this code to work for your needs.

myArray = nan(5,2)
mytable = array2table(myArray);
mytable.Properties.VariableNames = {'colA', 'colB'};
mytable2 = convertvars(mytable,"colB",'string');
mytable2.colA(:) = 459;
mytable2.colB(:) = "words"

You say you have a lot of data. If the variables already exist, you could do something like this:

colA = nan(5,1);
colB = strings(5,1);
mytable = table(colA,colB);
mytable.colA(:) = 459; % just a random number, proof-of-concept that it works
mytable.colB(:) = "words" % this throws errors
