Attempt to call constructor uitable with incorrect letter case

f = figure('Position',[100 100 400 150]);

dat = {6.125, 456.3457, true, 'Fixed';...

        6.75,  510.2342, false, 'Adjustable';... 

        7,     658.2,    false, 'Fixed';};

columnname = {'Rate', 'Amount', 'Available', 'Fixed/Adj'};

columnformat = {'numeric', 'bank', 'logical', {'Fixed' 'Adjustable'}};

columneditable = [false false true true];

t = uitable('Units','normalized','Position',...

            [0.1 0.1 0.9 0.9], 'Data', dat,... 

            'ColumnName', columnname,...

            'ColumnFormat', columnformat,...

            'ColumnEditable', columneditable,...

            'RowName',[]);

% this example from matlab help. When I run these codes I receive "Attempt to call constructor uitable with incorrect letter case" error.

It worked fine for me, after I got rid of your blank lines. Please read this: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup

Here's the code properly formatted:

f = figure('Position',[100 100 400 150]);
dat = {6.125, 456.3457, true, 'Fixed';...
  6.75,  510.2342, false, 'Adjustable';...
  7,     658.2,    false, 'Fixed';};
columnname = {'Rate', 'Amount', 'Available', 'Fixed/Adj'};
columnformat = {'numeric', 'bank', 'logical', {'Fixed' 'Adjustable'}};
columneditable = [false false true true];
t = uitable('Units','normalized','Position',...
  [0.1 0.1 0.9 0.9], 'Data', dat,...
  'ColumnName', columnname,...
  'ColumnFormat', columnformat,...
  'ColumnEditable', columneditable,...
  'RowName',[]);

It does not produce a "Attempt to call constructor uitable with incorrect letter case" error.

Tip: In MATLAB, type control-A then control-I to properly indent your code. Then in the Answers edit box, do not click {}Code first but paste in the code first. Then highlight the code and THEN click {}Code.
