remove cells border in a jtable

Question

I have my on custom cell renderer and want to remove the border of the cell.
How can i do it? I tried setBorder but it doesn't work.

Here is my renderer code:

public class MyTableCellRenderer extends DefaultTableCellRenderer {

    private static final long serialVersionUID = -1195682136616306875L;

    public Component getTableCellRendererComponent(JTable table, Object value,
            boolean isSelected, boolean hasFocus, int row, int column) {
        Component c = super.getTableCellRendererComponent(table, value,
                isSelected, hasFocus, row, column);
        if (!isSelected) {
            if (row % 2 == 0 && row != 1) {
                c.setBackground(new Color(255, 255, 150));
            } else {
                c.setBackground(Color.WHITE);
            }
        } else {
            c.setBackground(new Color(255, 230, 255));
        }
        c.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 0));
        return c;
    }
}

Answer 1

The lines drawn between cells are not part of the cells themselves. They are drawn by the table. You can turn them off for the entire table with:

table.setShowGrid(false);

To disable just the the horizontal or just the vertical lines:

table.setShowHorizontalLines(false);
table.setShowVerticalLines(false);

Or, you can change the color of the lines with:

table.setGridColor(color)

I don't know how your code compiles since only Swing components can have a Border and the Component class doesn't have a setBorder() method.

When I override the default renderer I use something like:

Class CustomRenderer extends DefaultTableCellRenderer
{
    public Component getTableCellRendererComponent(
        JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
    {
        super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        this.setBorder (BorderFactory.createBevelBorder (EtchedBorder.RAISED));
        return this;
    }
}
