我需要在特定列的单元格文本中的任何位置过滤我的Excel电子表格中的单词“GHH”。我设法做到这一点,然后我需要返回找到这个文本的整行。这我不能做,因为似乎没有办法使用getRowIndex
方法然后显示整排。
这是我的代码:
public static void main(String[] args) throws IOException {
FileInputStream fis = new FileInputStream(new File("myfile.xls"));
HSSFWorkbook workBook = new HSSFWorkbook(fis);
HSSFSheet sheet = workBook.getSheetAt(0);
Iterator < Row > rows = sheet.rowIterator();
while (rows.hasNext()) {
HSSFRow row = (HSSFRow) rows.next();
Iterator < Cell > cells = row.cellIterator();
while (cells.hasNext()) {
HSSFCell cell = (HSSFCell) cells.next();
if (cell.toString().contains("GHH")) {
String key = cell.getStringCellValue();
int RI = cell.getRowIndex();
}
}
}
workBook.close();
}

您可以尝试使用List<HSSFRow>
将过滤后的行保存为:
List<HSSFRow> filteredRows = new ArrayList<HSSFRow>();
Iterator<Row> rows= sheet.rowIterator();
while (rows.hasNext ()){
HSSFRow row = (HSSFRow) rows.next ();
Iterator<Cell> cells = row.cellIterator ();
while (cells.hasNext ()){
HSSFCell cell = (HSSFCell) cells.next ();
if (cell.toString().contains("GHH")) {
String key = cell.getStringCellValue();
int RI=cell.getRowIndex();
filteredRows.add(row);
break;
}
}
// then use filteredRows

您可能希望有两位逻辑,一位用于处理&#34;匹配&#34;行,一个用于匹配。类似的东西:
DataFormatter formatter = new DataFormatter();
public void matchingRow(Row row) {
System.out.println("Row " + (row.getRowNum()+1) + " matched:");
for (Cell c : row) {
System.out.println(" " + formatter.formatCellValue(cell));
}
}
public void handleFile(File excel) throws Exception {
Workbook wb = WorkbookFactory.create(excel);
Sheet sheet = wb.getSheetAt(0);
for (Row row : sheet) {
boolean matched = false;
for (Cell cell : row) {
if (matched) continue;
if (formatter.formatCellValue(cell).contains("GHH")) {
matchingRow(row);
matched = true;
}
}
}
}
这将检查第一张纸中的每个单元格,如果一行中单元格的文本与GHH
匹配,则会打印出行的内容。如果一行有两次,那么它只打印一次
