MATLAB Creating Graphical User Interfaces

Categorical Data

categorical values can appear as drop-down lists or as text. The categories appear in

drop-down lists when the ColumnEditable property of the Table UI component is

true. Otherwise, the categories display as text without a drop-down list.

f = uifigure;

cnames = categorical({'Blue';'Red'},{'Blue','Red'});

w = [400; 700];

tdata = table(cnames,w,'VariableNames',{'Color','Wavelength'});

uit = uitable(f,'Data',tdata,'ColumnEditable',true);

If the categorical array is not protected, users can add new categories in the running

app by typing in the cell.

Datetime Data

datetime values display according to the Format property of the corresponding table

variable (a datetime array).

f = uifigure;

dates = datetime([2016,01,17; 2017,01,20],'Format','MM/dd/uuuu');

m = [10; 9];

tdata = table(dates,m,'VariableNames',{'Date','Measurement'});

uit = uitable(f,'Data',tdata);
