JTable not showing in JPanel

I'm having a problem with displaying a JTable in a JPanel. I'm having the user press a button and within this button the table should generate the table and put in an already existing panel, now when I tried to open it in a new JFrame the data shows perfectly but I want to show it in a JPanel.

Code:

   files = c.RequestFile("list"); //gets the data of files
        Object[][] filesArray = new Object[files.size()][1];
        int size = 0;
        for (FileInfo fileInfo : files) {
            filesArray[size][0] = fileInfo.getName();
            size++;
        }

        fileTablePanel.setLayout(new BorderLayout());
        fileTablePanel.add(new JScrollPane(createTable(filesArray)));

You want to look into using a TableModel. What you are currently doing is trying to replace one JTable with another JTable. That is totally unnecessary. You should just manipulate the data of the TableModel.

You can see more at How to use Tables. You can focus on the section Creating a Table Model

You need to repaint the table like this

fileTablePanel.repaint();

After adding the new content to the panel, you need to repaint the panel to the screen:

fileTablePanel.revalidate();
fileTablePanel.repaint();

It works when you popup a new JFrame since it's the first time the JFrame is painted to the screen.
