Can't change row text in .docx file once row is added to table

I have the problem with the following code:



XWPFTable table = <get table somehow>;
CTRow firstRow = table.getRow(0).getCtRow();

for (int i = 0; i < data.getRowCount(); i++) {
CTRow ctRow = (CTRow) firstRow.copy();
XWPFTableRow row = new XWPFTableRow(ctRow, table);
XWPFRun cellRuns = row.getTableCells()
.stream()
.map(c -> c.getParagraphs().get(0))
.map(p -> p.getRuns().isEmpty() ? p.createRun() : p.getRuns().get(0))
.toArray(XWPFRun::new);
for (int j = 0; j < cellRuns.length; j++) {
cellRuns[j].setText(data.getValueAt(i, j).toString(), 0);
}
table.addRow(row);
}


table.getRow(1).getTableCells()
.get(0).getParagraphs()
.get(0).getRuns()
.get(0).setText("FooBar", 0); //change text in some added row


This code is copying the first row of the table several times and then copying values from data. Works perfectly fine (except text style) except the last operator, which was supposed to change the text in some added table row. Also, the "FooBar" string doesn't even appear in document.xml of created WORD document. I failed to see any clues from debug, because it seems, that table.addRow(row); operator just copies row pointer to it's internal list of rows. Also, I didn't have problems with altering already existing rows. So do you have any ideas why this could happen?

    Why don't you try changing your row text (to the "FooBar") in the inner for loop using an if condition while setting the text to the cellRuns array?

  • @Abhinav, I already did this, but I really want to understand what is wrong with the code. It doesn't seem right, cause when I change the existing row, it works. Also, values actually change in debugger after adding, theese changes just are not saved in the docx.

To reproducing the problem do having a source.docx having a first table having at least two rows.



Then do running following code:



import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.poi.xwpf.usermodel.*;

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTRow;

public class WordInsertTableRow {

static XWPFTableRow insertNewTableRow(XWPFTableRow sourceTableRow, int pos) throws Exception {
XWPFTable table = sourceTableRow.getTable();
CTRow newCTRrow = CTRow.Factory.parse(sourceTableRow.getCtRow().newInputStream());
XWPFTableRow tableRow = new XWPFTableRow(newCTRrow, table);
table.addRow(tableRow, pos);
return tableRow;
}

static void commitTableRows(XWPFTable table) {
int rowNr = 0;
for (XWPFTableRow tableRow : table.getRows()) {
table.getCTTbl().setTrArray(rowNr++, tableRow.getCtRow());
}
}

public static void main(String args) throws Exception {

XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx"));
boolean weMustCommitTableRows = false;

XWPFTable table = doc.getTableArray(0);

// insert new row, which is a copy of row 2, as new row 3:
XWPFTableRow sourceTableRow = table.getRow(1);
XWPFTableRow newRow3 = insertNewTableRow(sourceTableRow, 2);

// now changing something in that new row:
int i = 1;
for (XWPFTableCell cell : newRow3.getTableCells()) {
for (XWPFParagraph paragraph : cell.getParagraphs()) {
for (XWPFRun run : paragraph.getRuns()) {
run.setText("New row 3 run " + i++, 0);
}
}
}
System.out.println(newRow3.getCtRow()); // was changed
System.out.println(table.getRow(2).getCtRow()); // even this is changed
System.out.println(table.getCTTbl().getTrArray(2)); // but this was not changed, why not?
weMustCommitTableRows = true;

if (weMustCommitTableRows) commitTableRows(table); // now it is changed

FileOutputStream out = new FileOutputStream("result.docx");
doc.write(out);
out.close();
doc.close();

}
}


This code creates a copy of second row and inserts it as third row in the table. Then it does changing something in that new third row.



The issue ist, that the changings do appearing in low level CTRow of the row itself but do not appearing in low Level CTTbl of the table. For me this is not logically and I cannot get the reason of that. It looks as if the new CTRow elements are not part of the CTTbl at all. But they were added to it using ctTbl.setTrArray in XWPFTable.addRow. So I suspect there is something wrong with setTrArray in org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTbl. It seems updating the XML correctly but losing the object relations in the array (or list) of CTRows in CTTbl. But this is very hard to determining because of the kind of programming the org.openxmlformats.schemas classes. At least I was not able to do so. Maybe another of the professional and enthusiast programmers here may be able?



I am using the same approach for inserting rows having tthe same styling as a given source row. But after I have done this, I am setting boolean weMustCommitTableRows = true; and then I am doing if (weMustCommitTableRows) commitTableRows(table); before writing out the document. Then all changings will be committed.

        public class WordInsertTableRow {

        static XWPFTableRow insertNewTableRow(XWPFTableRow sourceTableRow, int pos) throws Exception {

        }

        static void commitTableRows(XWPFTable table) {

        XWPFTableRow sourceTableRow = table.getRow(1);
        XWPFTableRow newRow3 = insertNewTableRow(sourceTableRow, 2);

        // now changing something in that new row:
        int i = 1;
        for (XWPFTableCell cell : newRow3.getTableCells()) {
        for (XWPFParagraph paragraph : cell.getParagraphs()) {

        doc.write(out);
        out.close();
        doc.close();

        }
        }


        This code creates a copy of second row and inserts it as third row in the table. Then it does changing something in that new third row.



        The issue ist, that the changings do appearing in low level CTRow of the row itself but do not appearing in low Level CTTbl of the table. For me this is not logically and I cannot get the reason of that. It looks as if the new CTRow elements are not part of the CTTbl at all. But they were added to it using ctTbl.setTrArray in XWPFTable.addRow. So I suspect there is something wrong with setTrArray in org.openxmlformats.schemas.wordprocessingml.x2006.main.CTTbl. It seems updating the XML correctly but losing the object relations in the array (or list) of CTRows in CTTbl. But this is very hard to determining because of the kind of programming the org.openxmlformats.schemas classes. At least I was not able to do so. Maybe another of the professional and enthusiast programmers here may be able?



        I am using the same approach for inserting rows having tthe same styling as a given source row. But after I have done this, I am setting boolean weMustCommitTableRows = true; and then I am doing if (weMustCommitTableRows) commitTableRows(table); before writing out the document. Then all changings will be committed.

        To reproducing the problem do having a source.docx having a first table having at least two rows.



        Then do running following code:



        import java.io.FileInputStream;
        import java.io.FileOutputStream;
        import org.apache.poi.xwpf.usermodel.*;

        import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTRow;

        public class WordInsertTableRow {

        static XWPFTableRow insertNewTableRow(XWPFTableRow sourceTableRow, int pos) throws Exception {
        XWPFTable table = sourceTableRow.getTable();
        CTRow newCTRrow = CTRow.Factory.parse(sourceTableRow.getCtRow().newInputStream());
        XWPFTableRow tableRow = new XWPFTableRow(newCTRrow, table);
        table.addRow(tableRow, pos);
        return tableRow;
        }

        static void commitTableRows(XWPFTable table) {
        int rowNr = 0;
        for (XWPFTableRow tableRow : table.getRows()) {
        table.getCTTbl().setTrArray(rowNr++, tableRow.getCtRow());
        }
        }

        public static void main(String args) throws Exception {

        XWPFDocument doc = new XWPFDocument(new FileInputStream("source.docx"));
        boolean weMustCommitTableRows = false;

        XWPFTable table = doc.getTableArray(0);

        // insert new row, which is a copy of row 2, as new row 3:
        XWPFTableRow sourceTableRow = table.getRow(1);
        XWPFTableRow newRow3 = insertNewTableRow(sourceTableRow, 2);

        // now changing something in that new row:
        int i = 1;
        for (XWPFTableCell cell : newRow3.getTableCells()) {
        for (XWPFParagraph paragraph : cell.getParagraphs()) {
        for (XWPFRun run : paragraph.getRuns()) {
        run.setText("New row 3 run " + i++, 0);
        }
        }
        }
        System.out.println(newRow3.getCtRow()); // was changed
        System.out.println(table.getRow(2).getCtRow()); // even this is changed
        System.out.println(table.getCTTbl().getTrArray(2)); // but this was not changed, why not?
        weMustCommitTableRows = true;

        if (weMustCommitTableRows) commitTableRows(table); // now it is changed

        FileOutputStream out = new FileOutputStream("result.docx");
        doc.write(out);
        out.close();
        doc.close();

        }
        }


        This code creates a copy of second row and inserts it as third row in the table. Then it does changing something in that new third row.
