Hi,
I use HTML to format the text color in cells of a uitable, e.g.
set(table_handle, 'Data',{'<html><font color="red">cell contents'});
If I later try to change the contents of that cell using the setValueAt method of the table's underlying jTable, the HTML formatting isn't changed, i.e. when using
jTable.setValueAt('new cell contents',0,0)
the new cell contents is still formatted red and if I click the cell to start editing it, I see that the HTML code is still there.
Any ideas how to also overwrite the HTML code without having to re-write the whole table using set(table_handle, 'Data',...) ?
(By the way, I know it would be more elegant to use a custom cell renderer...)

Please show us, how you obtain jTable.

Sorry - I forgot that. Here is the code:
jscrollpane = findjobj(table_handle);
jTable = jscrollpane.getViewport.getView;

Maybe I should also mention that I try to set the cell value in the jTable's MousePressedCallback, i.e. in my GUI's OutputFcn I set
set(handle(jTable, 'CallbackProperties'), ...
'MousePressedCallback',{@table_MousePressedCallback, gcf});
and then later
function table_MousePressedCallback(jTable, jEventData, figure_handle)
...
jTable.setValueAt(newValue, jTable.rowAtPoint(jEventData.getPoint), jTable.columnAtPoint(jEventData.getPoint));
...

Hi Stephan,
I understand you are trying to achieve certain functionality in uitable but using findjobj. Not sure the purpose of using findjobj and the use case where its required to use the setValue function.
Alternatively you can use the matlab uitable directly to achieve the required functionality.
Here is the code -
ut = uitable('Data',{'<html><font color="red">cell contents'})
ut.Data{1,1} = 'cell contents'
Thanks, Vineeta

Hi Vineeta,
thank you for pointing me towards this elegant solution! Since I had developed my code in HG1-times, I never thought of this...
Thanks, Stephan.
