How to assign values for uitable using a for loop?
显示 更早的评论
Hi
I'm new to matlab. Currently I'm working with GUI. So I developed a code to visible a table to gather user inputs. That uitable has 2 columns. Number of rows is a user defined value n. Column 1 must have predefined values and column 2 must gather user input data to an array. I want to assign values from 1 to n for column 1 of uitable. So I tried with a for loop. This is my code.
n = str2num(get(handles.N,'String')); % get number of stories from user
set(handles.table1,'visible','on')
ndata = cell(n,2);
set(handles.table1, 'data',ndata);
for i=1:1:n
set(handles.table1(i,1),'String',i);
Following error occurred.
The name 'String' is not an accessible property for an instance of class 'uitable'
Can anyone tell me what should be the modification here?
Thank You

Did you read the help documentation for uitable? If not why not?, if so why are you trying to assign 'String' in a table? 'Data' is the property you should be setting.

This is based on pure guessing, isn't it? Neither handles.table1(i,1) nor the 'String' property is meaningful. Did you read the documentation already?
doc uitable
You cannot set a 'String' property to a number. Defining the 'data' was the right way already:
ndata = cell(n,2);
for k = 1:n
ndata{k,1} = k;
end
set(handles.table1, 'data', ndata);
Avoid "i" and "j" as names of variables, see https://www.mathworks.com/matlabcentral/answers/46648-using-i-and-j-as-variables

It depends on what "get values from the user" and "assign values in an array" means.How do you want to get the values? Through a GUI, input, from a function or just by editing the uitable? When and where should the values be assigned to an array?
