Essential Data's MROTable is designed to do this.

Here's the MROTable example from the Essential Data's doc rewritten to have
headers on each row:

    // Replace the appropriate parts of View.java with this:

    private int[] getColumnWeights() {
        return new int[] {25, 25, 10, 20, 20};
    }

    private class ContactsRowFactory implements IPartControlFactory {
        public Composite createPartControl(Composite parent) {
            Color white =
Display.getDefault().getSystemColor(SWT.COLOR_WHITE);
    
            // The row Composite
            Composite part = new Composite(parent, SWT.NULL);
            part.setBackground(white);
            part.setLayout(new FillLayout(SWT.VERTICAL));
            
            // Include the header on each row
            Composite rowHeader = new Composite(part, SWT.NULL);
            rowHeader.setLayout(new TableLayout(getColumnWeights(),
SWT.CENTER | SWT.BORDER));
            new Label(rowHeader, SWT.NULL).setText("First Name");
            new Label(rowHeader, SWT.NULL).setText("Last Name");
            new Label(rowHeader, SWT.NULL).setText("Age");
            new Label(rowHeader, SWT.NULL).setText("Phone");
            new Label(rowHeader, SWT.NULL).setText("Gender");
    
            // The actual SWT editor objects
            Composite row = new Composite(part, SWT.NULL);
            row.setBackground(white);
            row.setLayout(new TableLayout(getColumnWeights(), SWT.CENTER |
SWT.BORDER));
            new Text(row, SWT.NULL).setData("boundTo", "FirstName");
            new Text(row, SWT.NULL).setData("boundTo", "LastName");
            new Text(row, SWT.NULL).setData("boundTo", "Age");
            new Text(row, SWT.NULL).setData("boundTo", "PhoneNumber");
            new Combo(row, SWT.READ_ONLY).setData("boundTo", "Gender");
            
            return part;
        }
    }

Actually, running this code shows a few minor bugs in the keyboard handling
that I'll fix.  The fix should be in CVS this afternoon.
