what about if I would like to set a specific background and font color to the table row header?

how can I define a callback for a cell/row/column selection? In createTable you can define a data changed callback, but if you simply select a cell, how can you define a callback?

Thanks

Maurizio

headers is a simple cell array of strings (column header names). I thought that was pretty obvious from the context…

Additional types of uitable customizations are described in other articles on this website, and in my book (“Undocumented Secrets of Matlab-Java Programming“), and in my Uitable Customization Report. If you’d like personal assistance with your specific project, I’d be happy to help you as a professional consultant.

i’m trying to use your code example to change the colors of a table cell, but I have a doubt: in the following part of your code:

% Yellow background for significant rows based on p-value
if data(rowIdx,12)<=5 && data(rowIdx,11)~=0
    for colIdx = 1 : length(headers)
      cr.setCellBgColor(rowIdx-1,colIdx-1,java.awt.Color(1,1,0));    % yellow
    end

what is "headers"? It is not defined, so I don't know what to do when I call

jTable.setModel(javax.swing.table.DefaultTableModel(dataCells,headers));

Is it a cell array containing the columns name? Can you explain?

I don't know java language, so I have some problem to understand the code, I built a java table using your "createTable.m" code, but there isn't any example to how to change cell color or font.

Thank you

Philip – perhaps you forgot to update the table’s model to a DefaultStyleTableModel. In any case, this topic is way outside the scope of this blog, which is Matlab-centric – It relates to a pure Java component that is covered in the JIDE documentation and forums, so I will not discuss it in any detail here.
If you’d like my additional assistance in your specific case, please contact me by email for a private consulting proposal.

I am a bit of a novice at programming with Java. Would you please expound a bit more or provide an example on how to use JIDE’s CellStyle in MATLAB? I have successfully created a CellStyle object and set its properties in MATLAB. I used your uiinspect tool to verify that the object was created and props were set appropriately but have been unable to assign the object to specific cells. Methods like setCellStyle(int, int, com.jidesoft.grid.CellStyle) do not appear to be valid. I have read through the JIDE Grids Developer Guide but have not found it to be very helpful for my purpose. I have also read through your Uitable Customization Report but it does not provide any detail on the use of CellStyle.

@Philip – in the Java-based uitable you can use JIDE’s CellStyle to customize specific cells. Refer to JIDE’s documentation for details.
In the web-based (uifigure/AppDesigner) uitable, you can use the uistyle function starting in R2019b.

You may have addressed this already in the past, if so, please kindly point me to the appropriate article(s). My issue is with creating a table which has (not column but) cell specific renderers, editors, and editability. Therefore cells within the same column use different renderers, editors, and may or may not be editable. What adds further complexity is that I have a table who’s rows may or may not span multiple columns. I can upload / email my code if this helps.

Philip

thank you.
