我有2行5列excel。现在我手动输入代码以从第1行获取值。我该如何重复这个过程?
以下是excel第一行的代码。从第2行开始,我不知道该怎么做......我想迭代一行。
Workbook workbook = Workbook.getWorkbook(new File(
"\\C:\\users\\a-4935\\Desktop\\DataPool_CA.xls"));
Sheet sheet = workbook.getSheet("Sheet1");
System.out.println("Reached to Sheet");
Cell a = sheet.getCell(2,1);
Cell b = sheet.getCell(3,1);
Cell c = sheet.getCell(4,1);
Cell d = sheet.getCell(5,1);
Cell e = sheet.getCell(6,1);
Cell f = sheet.getCell(7,1);
Cell g = sheet.getCell(8,1);
Cell h = sheet.getCell(9,1);
Cell i = sheet.getCell(10,1);
String uId = a.getContents();
String deptFromDat = b.getContents();
String deptToDate = c.getContents();
String dept1 = d.getContents();
String arrival1 = e.getContents();
String eihon1 = f.getContents();
String branchCode1 = g.getContents();
String userType1 = h.getContents();
String sessionId1 = i.getContents();

使用以下代码迭代数据表的所有行:
Sheet sheet = workbook.getSheet("Sheet1");
for (Row row : sheet) {
for (Cell cell : row) {
//your logic
}
}
或者,使用以下代码:
Sheet sheet = workbook.getSheet("Sheet1");
for (int i = 0; i < 2; i++) {
Row row = sheet.getRow(i);
if(row == null) {
//do something with an empty row
continue;
}
for (int j = 0; j < 5; j++) {
Cell cell = row.getCell(j);
if(cell == null) {
//do something with an empty cell
continue;
}
//your logic
}
}

您只需将1更改为行号,然后使用for循环。 根据您的代码,您可以执行以下操作,例如: 例如:
for(int i=0; i<number; i++)
{
Cell a = sheet.getCell(2,i);
Cell b = sheet.getCell(3,i);
Cell c = sheet.getCell(4,i);
...
}
或者更好的是将Cell声明移出for循环,这是更好的做法。
Cell a,b, c...;
for(int i=0; i<number; i++)
{
a = sheet.getCell(2,i);
b = sheet.getCell(3,i);
c = sheet.getCell(4,i);
...
}

function myFunc(elem)
{
$(elem).find('svg').attr('preserveAspectRatio','none'); // doesn't work
}
您可以使用上面的代码迭代所有行和所有单元格
