用OpenCSV在JTable中显示CSV文件

Question

我想使用OpenCSV库将CSV文件导入到JTable中。网上找到的所有例子都与命令行显示有关，这里找到的唯一代码不起作用，因为JTable需要Object[][]和String[]:

CSVReader reader = new CSVReader(new FileReader("yourfile.csv")); 
List myEntries = reader.readAll();
JTable table = new JTable(myEntries.toArray());

来源:将csv导入JTable

有没有办法用这个库把这些文件显示在一个表格里？

我用这个代码解决了它

import com.opencsv.*;

private Object[] dataColumn;
private DefaultTableModel tableModel = new DefaultTableModel();

    tableModel = (DefaultTableModel) tblFontName.getModel();

            CSVReader reader = new CSVReaderBuilder(new FileReader(fontDB))
                    .withCSVParser(new CSVParserBuilder()
                            //.withQuoteChar('\'')
                            .withSeparator('\t')
                            .build())
                    .build();
            List myEntries = reader.readAll();
            dataColumn = (String[]) myEntries.get(0);
            tableModel = new DefaultTableModel(dataColumn, myEntries.size()-1); 
            int rowcount = tableModel.getRowCount();
            for (int x = 0; x<rowcount+1; x++){
                int columnnumber = 0;
                // if x = 0 this is the first row...skip it... data used for columnnames
                if (x>0){
                    for (String thiscellvalue : (String[])myEntries.get(x)){
                        tableModel.setValueAt(thiscellvalue, x-1, columnnumber);
                        columnnumber++;
                    }
                }
            }
            reader.close();
