I am unable to make my JTable/JScrollPane so that it gains horizontal

Any suggestions?

SSCCE

import java.awt.BorderLayout;

public class HorizScrollTable extends JPanel {

HorizScrollTable() {

column.setPreferredWidth(width);
column.setMinWidth(width); // [2]

JPanel p = new JPanel(new BorderLayout());
p.add(table, BorderLayout.CENTER); // [3]

Thanks, that is perfect in all but one respect ...
Unfortunately the table headings no longer show.

In case I've misread your message, here is my revised constructor:

HorizScrollTable() {
setLayout(new BorderLayout());
JTable table = new JTable(data, headings); // headings!

for (int i = 0; i < headings.length; i++) {
TableColumn column = table.getColumnModel().getColumn(i);
int width = widths[i];
column.setPreferredWidth(width);
column.setMinWidth(width);
}

JPanel p = new JPanel(new BorderLayout());
p.add(table, BorderLayout.CENTER);
p.setPreferredSize(table.getPreferredSize());
JScrollPane scrollPane = new JScrollPane(p);

add(scrollPane, BorderLayout.CENTER);
}

(new readers please see first posting in thread for original SSCCE in full)

Is it impossible to have horizontal scrolling AND headings?

By setting the header explicitly on the scrollPane you can have
headers:

scrollPane.setColumnHeaderView(table.getTableHeader());
