【中文标题】如何将数据从excel导入jTable？【英文标题】：how to import datas from excel to jTable? 【发布时间】：2015-07-02 11:42:22 【问题描述】：JFileChooser fc = new JFileChooser();
int option = fc.showSaveDialog(NewJFrame1.this);
if(option == JFileChooser.APPROVE_OPTION)
String filename = fc.getSelectedFile().getName();
String path = fc.getSelectedFile().getParentFile().getPath();
int len = filename.length();
String ext = "";
String file = "";
if(len > 4)
ext = filename.substring(len-4, len);
if(ext.equals(".xls"))
file = path + "\\" + filename;
else
file = path + "\\" + filename + ".xls";
toExcel(jTable1, new File(file));
这就是我将表格保存到 excel 的方法，它工作正常，但我想在重新启动程序后导入这些数据，有人可以帮我解决这个问题吗？
【问题讨论】：
【参考方案1】：您可以使用 Apache POI 导出您的 JTable 数据。

【参考方案3】：try
jxl.Workbook workbook = jxl.Workbook.getWorkbook(file);
jxl.Sheet sheet = workbook.getSheet(0);
headers.clear();
for (int i = 0; i < sheet.getColumns(); i++)
jxl.Cell cell1 = sheet.getCell(i, 0);
headers.add(cell1.getContents());
data.clear();
for (int j = 1; j < sheet.getRows(); j++)
Vector d = new Vector();
for (int i = 0; i < sheet.getColumns(); i++)
jxl.Cell cell = sheet.getCell(i, j);
d.add(cell.getContents());
d.add("\n");
data.add(d);
catch (Exception e)
e.printStackTrace();
这就是我解决问题的方法，希望对其他人有所帮助
