Usage

From source file:Main.java

public static void main(String[] args) {
    String[] headers = { "column 1", "column 2", "column 3", "column 4" };
    int cols = 4;

    for (int row = 0; row < rows; row++) {
        for (int col = 0; col < cols; col++) {
            data[row][col] = "item " + (row * cols + col + 1);
        }/*from   w  ww  . j ava2  s . c  o m*/
    }
    JTable table = new JTable(data, headers);
    DefaultTableCellRenderer renderer = (DefaultTableCellRenderer) table.getDefaultRenderer(String.class);
