我想知道如何使用xls
文件的片段並使用代碼片段(單元格,行)的元素進行操作。如何在Apache Poi上使用子表格?
我不用整行工作。
這裏的文件尋找:
我只需要與片斷進行操作,如:
下面是代碼片段與JXL
工作:
public class AncillariesWithPoi {
private Workbook workbook;
private EntryParser shortParser;
private EntryParser longParser;
private Sheet sheet;
private Cell lowShortStart;
private Cell lowShortEnd;
private Cell highShortStart;
private Cell highShortEnd;
private Cell lowLongStart;
private Cell lowLongEnd;
private Cell highLongStart;
private Cell highLongEnd;
public void setDefault() {
setRowKey(new CellReference("C30"), new CellReference("AR30"));
setLowSeasonShort("D30", "U40");
setHighSeasonShort("W30", "AN40");
setLowSeasonLong("AR30", "BI42");
setHighSeasonLong("BK30", "CC42");
}
public void setRowKey(CellReference firstRef, CellReference lastRef) {
shortParser.rowKey = firstRef.getCol();
longParser.rowKey = lastRef.getCol();
}
public void setLowSeasonShort(String startCell, String endCell) {
this.lowShortStart = sheet.getCell(startCell);
this.lowShortEnd = sheet.getCell(endCell);
}
public void setHighSeasonShort(String startCell, String endCell) {
this.highShortStart = sheet.getCell(startCell);
this.highShortEnd = sheet.getCell(endCell);
// ommited rest of
如何在apachte poi上使用子表格?
Generall我想知道如何實現下一個方法與apache poi
API:
public void setLowSeasonShort(String startCell, String endCell) {
this.lowShortStart = sheet.getCell(startCell);
this.lowShortEnd = sheet.getCell(endCell);
}
一個posibility,我發現在poi
:
for (Row row : sheet1) {
for (Cell cell : row) {
CellReference cellRef = new CellReference(row.getRowNum(), cell.getColumnIndex());
System.out.print(cellRef.formatAsString());
System.out.print(" - ");
switch (cell.getCellType()) {
// work with cell content
}
}
}
它是細胞迭代從表的每一行。如何將setLowSeasonShort(String startCell, String endCell)
改寫爲poi api
?
有什麼建議嗎?
這是不是很清楚你想達到什麼。代碼本身似乎已經使用POI。您已傳入開始和結束單元格引用。你想迭代該範圍(https://poi.apache.org/apidocs/org/apache/poi/ss/util/CellRangeAddress.html)嗎? –
@GáborBakos是的,並與這個子表一起工作。 –
