[英]Exporting JTable to excel - escaping the value of the next column
In my file writer, I have these codes, the j == 4 and j == 8 is to execute a different code for the column that contains numbers 在我的文件编写器中,我有以下代码,j == 4和j == 8是为包含数字的列执行不同的代码
for(int i=0; i<model.getRowCount();i++){
for(int j=0; j<model.getColumnCount();j++){
if(j==4 || j==8){
excelWriter.write("\""+model.getValueAt(i, j) + "\t"+"\"");
}
else{
excelWriter.write(model.getValueAt(i, j) + "\t");
}
}
excelWriter.write("\n");
}
the problem is after that column with number had been printed, the next column will not be printed.. for example 问题是在打印带有编号的列之后,将不打印下一列。
This is my JTable
| texta | textb | textc | textd | number | texte | textf | .......
in the excel file, it will be printed as....
| texta | textb | textc | textd | number | textf | .......
it skips the column beside the column with number... 它跳过带有数字的列旁边的列...
when i remove the 2nd "\\" in the code, the rest of the column concatenate to the column with number. 当我在代码中删除第二个“ \\”时,该列的其余部分将连接到具有数字的列。
Any idea how could I fix this? 知道我该如何解决吗? Thanks in advance 提前致谢
The second \\
have to be written before \\t
I would guess. 第二个\\
有之前写\\t
我猜。
Wait... I have created an Excel sheet with text columns and number columns. 等等...我创建了一个带有文本列和数字列的Excel工作表。 Then I exported that sheet to a tab separated file. 然后,我将该工作表导出到制表符分隔的文件中。 When I open that file in a text editor the number isn't escaped on any kind. 当我在文本编辑器中打开该文件时,该数字不会以任何形式转义。 So I don't think you need this if
. 所以我认为如果不需要的if
。
您可能的意思是:
excelWriter.write("\"" + model.getValueAt(i, j) + "\"\t");
for example, File can be with .xsl or .xlsx 例如,文件可以使用.xsl或.xlsx
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import javax.swing.JTable;
import javax.swing.table.TableModel;
