Hi Doug.

I have a popup menu and a table. Popup menu is to select a generator that will be used by the user. For example if the user wants to use 2 generators, then the user may select ’2 ‘on the popup menu. If the user select 2, then the table will be issued a 2 by 3 table. If users select three generators, then the table will be issued a 3 by 3 table. If users select four generators, then the table will be issued a 4 by 3 table and so on. My question is how i want this situation applies? What I mean is how to produce a 2 by 3 table when the user select ’2′ and 3 by 3 table when the user select ’3′ and so on?

For your info, My project is about economic dispatch. I have to build GUI using 4 generators and each of the generator have limit. So i have to make 2 uitables. So each generator user selected, then the user have to insert limit( in megawatt) for each generator(which is another table)

This is the example of my table(4 by 3):

Alpha Beta Gamma

The equation for the generator is :

C1 = (Alpha) + (Beta)P + (Gamma)P^2

C2 = (Alpha) + (Beta)P + (Gamma)P^2

C3 = (Alpha) + (Beta)P + (Gamma)P^2

C4 = (Alpha) + (Beta)P + (Gamma)P^2

This is a table for the limit of each generator:

Lower Upper

The form of this table will be :

Lower < C1 < Upper

Lower < C2 < Upper

Lower < C3 < Upper

Lower < C4 < Upper

So when the user select ’2′, then it will popup the 2 by 3 table. How i want to do it? What is the code for it and how i want to call the table data into the pushbuttons? Well i already make 2 uitable figures and i already set the table properties like the row name n column name. But how i want to make it only 2 row only?

Please do help me on this.

Hi Doug,
I did the following;
I added a row to expand the table as below;
data = get(handles.Data_table,’Data’);
newRow = cat(1,data,cell(1,size(data,2)));
set(handles.Data_table,’Data’,newRow);

this adds a row but the checkbox is not editable. So i added below lines but still i did not work;
Editable =[true,true,true,true,true,true,true];
set(handles.Data_table, ‘ColumnEditable’,Editable)
this problem is only for new added rows.

Regards,
Sunita

@Sunita,

Have you tried changing “editable” programatically?

Problem making checkbox and pup-up box editable:
I created uitable in GUI app containing checkbox, pup-box and numeric format and enabled the ‘Editable’ checkobx in Table Property editor. I can edit all formats in the GUI, however if i add an additional row though my program in m-file the numberic cell is still editable but the checkbox and pop-ups are not. How can i make these format editable.

Sunita

@Tzu-hao

Are you finding that the property that controls justification is changing? Is it different for strings vs numerical data?

Dear Doug

Thank you for this useful demonstration. One issue I ran into while setting up a table is that I found if we pre-assign values into the table, when the values are later edited, it will align to the right. Otherwise it will align to the left. Is there a way to enforce the edited data to always align to the center (since I want to assign values to only a portion of the boxes).

Thanks
Tzu-hao

Yana,

Each column will have one set of choices for the choice menu. You can not vary it by row.
