MATLAB中uitable控件data属性

lvjiangtaoshawn

h=figure;
a1=[1 2 3]';
b1={'5' '6' '7'}';
a={a1,b1};
uitable('data',a,'parent',h,'position',[100 100 300 100],'columnformat',{'numeric','char'});
  运行的时候出错了
Error using ==> uitable
Data within a cell array must have size [1 1]
Error in ==> uitable at 56
        thandle = builtin('uitable', varargin{:});
我是刚学习MATLAB不久的菜鸟，请哪位大师叫我如何解决这个问题  ，谢谢
