如何使用NatTable导出接口按条件导出表数据？

// 获取筛选后的数据
List<Object[]> filteredData = getFilteredData();

// 创建一个文件选择对话框，选择导出文件的位置和名称
FileChooserDialog fileChooser = new FileChooserDialog(shell, SWT.SAVE);
fileChooser.setFilterExtensions(new String[] { "*.csv" });
String exportFilePath = fileChooser.open();

// 导出数据到CSV文件
try (BufferedWriter writer = new BufferedWriter(new FileWriter(exportFilePath))) {
    // 写入表头
    for (int columnIndex = 0; columnIndex < columnCount; columnIndex++) {
        writer.write(natTable.getColumnHeaderData(columnIndex) + ",");
    }
    writer.newLine();

    // 写入数据
    for (Object[] rowData : filteredData) {
        for (int columnIndex = 0; columnIndex < columnCount; columnIndex++) {
            writer.write(rowData[columnIndex].toString() + ",");
        }
        writer.newLine();
    }
} catch (IOException e) {
    e.printStackTrace();
}
