How do you set a JLabel to take all the available width space?

I'm trying to center the JLabel text and to change the background and foreground color. I tried to use HTML:

JLabel listHeader = new JLabel("<html><span style='background-color:#555;color:White;text-align:center;'>Tables</span></html>");

But it doesn't seem to work as you can see in the image below.

The label is inside a panel that has the layout manager set to grid bag layout with the following constraints:

c.gridy=0;
c.gridx=0;
c.weighty=0;
c.weightx=1;
c.fill=GridBagConstraints.NONE;
c.anchor = GridBagConstraints.LINE_START;

I tried with fill BOTH as well, same result.

How can I make the label take all the width space?

I tried to use HTML:

Don't use HTML.

I'm trying to center the JLabel text

To center the text in the space available to the label you can use:

label.setHorizontalAlignment(JLabel.CENTER);

and to change the background and foreground color.

You need to make the label opaque:

label.setOpaque( true ):
label.setBackground( Color.RED );

I tried with fill BOTH as well, same result.

Well, I don't think you want "BOTH" since you are only concerned with the width. You may also need to use the weightx constraint. Read the section from the Swing tutorial on How to Use GridBagLayout for more information on using the constraints.

Without your MCVE/SSCCE we can't see exactly what you are doing.

You could try to anchor at the center, not on the start of the line.
