Is there a way to center the data in a uitable, maybe through the underlying Java?

I've been trying through the JTable interface, this is what I have so far:

table = findjobj(handles.cutTable); %findjobj is in the file exchange
table1 = get(table,'Viewport');
jtable = get(table1,'View');
renderer = jtable.getCellRenderer(2,2);
renderer.setHorizontalTextPosition(javax.swing.swingConstants.CENTER);

This doesn't throw any errors, but it also doesn't seem to change anything. I eventually want to set all the cells to center. What am I doing wrong? My Java isn't good, and I've never tried doing anything with the underlying Java in Matlab before.

It works if I set both text and alignment together:

table = findjobj(handles.cutTable); %findjobj is in the file exchange
table1 = get(table,'Viewport');
jtable = get(table1,'View');
renderer = jtable.getCellRenderer(2,2);

renderer.setHorizontalTextPosition(javax.swing.SwingConstants.CENTER);
renderer.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);

I used the above code by Suwen (but I substituted handles.cutTable for the handle of the uitable I created) but I wasn't able to get the text to center. Does anyone have any hints on how I can get the code to center text in my uitable?

Java table cell renderers are only effective on the old (pre-R2008a) uitable; in the new uitable, they get overridden by the data model (which is a big no-no BTW, the mathworker who did this needs to go back to school). I explain all this (plus how to fix it) in my uitable customization report:
http://UndocumentedMatlab.com/blog/uitable-customization-report/

The basic idea is to replace the new uitable's data model with a DefaultTableModel, after which renderers will start working.

I found something that seems to work without changing the data model. I got this to work in Matlab 2012a. It centers the text for all the cells.

figure;tableHandle = uitable;
set(tableHandle,'Data',rand(5,2))

jscrollpane = findjobj(tableHandle);
jTable = jscrollpane.getViewport.getView;

cellStyle = jTable.getCellStyleAt(0,0);
cellStyle.setHorizontalAlignment(cellStyle.CENTER);

% Table must be redrawn for the change to take affect
jTable.repaint;

I want something similar but only change certain rows/columns, is that possible?

Thanks for replying. Unfortunantly, im a bit confused: im using guide/java (like the code above) so changing my already made code into html is not desirable. Is something similar possible via java as above? Something like:

cellStyle = jTable.getCellStyleAt(1,1);
cellStyle.setHorizontalAlignment.Range(1:3).(cellStyle.LEFT);
cellStyle.setHorizontalAlignment.Range(4:10).(cellStyle.RIGHT);

Thanks

Works beautifully in R2018a as well. Cheers! Much neater solution than html and associated parsing.
