- Hi Every One
- I've a pdf report generated with iText containing a PdfPTable added to MultiColumnText, sometimes becomes so large that it will be split on more than one page,
- Here am added sample Code, Its working as
Page -1
--------------------------------------------------------------------------------------------------------------------------------------------------+ | 1st - Emp1-NO | 2nd - Emp1-Name| 3rd - Emp1-Desig |
| 4th - Emp2-NO | 5th - Emp2-Name| 6th - Emp2-Desig |
| 7th - Emp3-NO | 8th - Emp3-Name| 9th - Emp3-Desig |
--------------------------------------------------------------------------------------------------------------------------------------------------+
but i want fill the data as first No all rows then each columns i.e. column by column
Like below
Page -1
--------------------------------------------------------------------------------------------------------------------------------------------------+ | 1st - Emp1-NO | 4th - Emp1-Name| 7th - Emp1-Desig |
| 2nd - Emp2-NO | 5th - Emp2-Name| 8th - Emp2-Desig |
| 3rd - Emp3-NO | 6th - Emp3-Name| 9th - Emp3-Desig |

Question Updating
I have 150 Employees Data
Each Employee Have Name & InTime & OutTime
Please find the PDF Image
I Need Help on Logic of cell fill as a. Print Employee Ids in 1st Column - 150 employees b. Then already printed each row 2nd Column with Employee Name c. Then print with In time 3rd Column
Simply From - First Print 3 rows with 1st Column [1066,1067,1069] Ids Then again Print again Exiting 3 rows 2nd Column[Name-ABCD, Name-XYZ, Name-PQR]..etc
ConcurrentHashMap<String,EmpHistory> emp_HistoryList = new ConcurrentHashMap<String, EmpHistory>();
emp_HistoryList = this.getHistoryData();
for(EmpInfo emp : empInfoList){
empHistory = emp_HistoryList.get(emp.getId());
//Print all 105 Emps rows with IDs in 1st Column
//Print each Emp row Name and IN time column
}
Question Update - 2
- I am using Java with iText
- I need to put text in columns,
- I Created PDFTable as :
PdfPTable table = new PdfPTable(33); - The problem is that PdfPTable fills the table row by row, that is, you first give the cell in column 1 of row 1, then column 2 of row 1, and so on, but I need to do it column by column, because that is how the data is being fed to me.
I Need Like as :
1 3 5
2 4 6
- present code working as
1 2 3
4 5 6
- please may i know where i did changes from my example code
- please help on this, thanks in Advance.
回答1:
For logical reasons, tables are filled row by row in iText:
If you want to change the order, you need to do this yourself by creating a data matrix first. One way to do this, is by creating a two-dimensional array (there are other ways, but I'm using an array for the sake of simplicity).
The RowColumnOrder example shows how it's done.
This is the normal behavior:
document.add(new Paragraph("By design tables are filled row by row:"));
PdfPTable table = new PdfPTable(5);
table.setSpacingBefore(10);
table.setSpacingAfter(10);
for (int i = 1; i <= 15; i++) {
table.addCell("cell " + i);
}
document.add(table);
You want to change this behavior, which means that you have to create a matrix in which you change the order rows and columns are filled:
String[][] array = new String[3][];
int column = 0;
int row = 0;
for (int i = 1; i <= 15; i++) {
if (column == 0) {
array[row] = new String[5];
}
array[row++][column] = "cell " + i;
if (row == 3) {
column++;
row = 0;
}
}
As you can see, there is no iText code involved. I have 15 cells to add in a table with 5 columns and 3 rows. To achieve this, I create a String[3][5] array of which I fill every row of a column, then switch to the next column when the current column is full. Once I have the two-dimensional matrix, I can use it to fill a PdfPTable:
table = new PdfPTable(5);
table.setSpacingBefore(10);
for (String[] r : array) {
for (String c : r) {
table.addCell(c);
}
}
document.add(table);
As you can see, the second table in row_column_order.pdf gives you the result you want.
回答2:
Basically @Bruno Lowagie said everything that is required.
The thing is, you know exactly what columns you want to print, so just do it like this, so you don't need to convert your map into a two dimensional array:
private static PdfPTable rawDataTable() throws DocumentException {
...
// outer loop for your rows
for (int i = 0 ; i < emp_HistoryList.size() ; i++) {
for (int j = 0 ; j < emp_HistoryList.values() ; j++) {
EmpHistory item = emp_HistoryList.get(j);
Cell cell;
switch (j) {
// I don't know your data types, so you might not need to convert.
case 0: cell = new PdfPCell(
new Phrase(String.valueOf(item.getId()));
break;
case 1: cell = new PdfPCell(
new Phrase(String.valueOf(item.getName()));
break;
// ... create cell with all the data you require of the 33 columns
default: cell = new PdfPCell(
new Phrase(""));
}
table.addCell(cell)
}
}
