swt table增加和删除行，第一列为ccombo控件，第二列为String，完整代码和注释

下面是 SWT Table 添加和删除行的示例代码，其中第一列使用了 CCombo 控件，第二列是一个字符串：

import org.eclipse.swt.SWT;
import org.eclipse.swt.events.SelectionAdapter;
import org.eclipse.swt.events.SelectionEvent;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.CCombo;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.widgets.Table;
import org.eclipse.swt.widgets.TableColumn;
import org.eclipse.swt.widgets.TableItem;

public class TableExample {

    public static void main(String[] args) {
        Display display = new Display();
        Shell shell = new Shell(display);
        shell.setText("SWT Table Example");

        shell.setLayout(new GridLayout(2, false));

        // create a label for the combo box
        Label label = new Label(shell, SWT.NONE);
        label.setText("Select an option:");

        // create a combo box with some options
        CCombo combo = new CCombo(shell, SWT.READ_ONLY);
        combo.setItems(new String[] { "Option 1", "Option 2", "Option 3" });

        // create a button to add a new row to the table
        Button addButton = new Button(shell, SWT.PUSH);
        addButton.setText("Add Row");

        // create a button to delete the selected row from the table
        Button deleteButton = new Button(shell, SWT.PUSH);
        deleteButton.setText("Delete Row");

        // create a table with two columns
        final Table table = new Table(shell, SWT.BORDER | SWT.MULTI | SWT.FULL_SELECTION);
        table.setLinesVisible(true);
        table.setHeaderVisible(true);

        GridData data = new GridData(SWT.FILL, SWT.FILL, true, true);
        data.horizontalSpan = 2;
        table.setLayoutData(data);

        TableColumn column1 = new TableColumn(table, SWT.NONE);
        column1.setText("Option");
        column1.setWidth(100);

        TableColumn column2 = new TableColumn(table, SWT.NONE);
        column2.setText("Text");
        column2.setWidth(100);

        // add a new row to the table when the add button is clicked
        addButton.addSelectionListener(new SelectionAdapter() {
            public void widgetSelected(SelectionEvent e) {
                TableItem item = new TableItem(table, SWT.NONE);
                item.setText(0, combo.getText());
                item.setText(1, "New Row");
            }
        });

        // delete the selected row from the table when the delete button is clicked
        deleteButton.addSelectionListener(new SelectionAdapter() {
            public void widgetSelected(SelectionEvent e) {
                int index = table.getSelectionIndex();
                if (index != -1) {
                    table.remove(index);
                }
            }
        });

        shell.pack();
        shell.open();

        while (!shell.isDisposed()) {
            if (!display.readAndDispatch()) {
                display.sleep();
            }
        }
        display.dispose();
    }
}

在这个示例代码中，我们创建了一个包含两列的 SWT Table。第一列使用了 CCombo 控件，用户可以从预定义的选项中选择一个值。第二列是一个字符串，用户不需要输入。我们还添加了一个 "Add Row" 按钮，当用户单击它时，将添加一个新行到表中。我们还添加了一个 "Delete Row" 按钮，当用户单击它时，将删除选中的行。
