I am trying to read the table styles that is in a pptx template.
Tried using XSLFTableStyle xslfTableStyle = xslfTableStyles.getStyles() but that returns empty list.
I am able to see the file which has the table styles in the pptx package in the location ppt/tableStyles.xml which has the styles for all the available tables and also the selected style for this template.
Even if I write some custom code to read this xml, I don't see a way to create a table in a slide using this style. XSLFTable tbl = tableSlide.createTable(); this does not take any style inputs
Any out of the box way to create a table using the available table style?
Think this is not yet developed by Apache POI team, should be in their roadmap
Thanks,

I am currently trying to create a .docx Document using docx4j.
I have already created a few tables, and want to change the background- and text-color of the first table row.
table in question
I would like to create a void function which gets a Tc (table cell) and String (color) as an argument.
I actually havent found any help online.
Thanks in advance :)
You could use the Docx4j Helper WordAddin or webapp to generate Java code from a suitable example docx.
I have a requirement where I need to generate a PDF document in Java using iText.
The ask is to use a PDF template, and inject the data values in a user designed PDF template to produce the desired output PDF.
The documentation on the iText site is not clear/or I didnt search them completely, so asking for support or article regarding this,
Our use case is to generate a table from a PDF template, where the number of rows is determined by the data (i.e. in here JSON). I should be able to dynamically scale the number of rows in a PDF template based on the data size.
Is this possible?
I was referring to this article:
https://github.com/koendehaen/itext_summit_pdf_templates
In the above GITHUB example, the rows were prepopulated in the PDF template, I want something like the below screenshot, similar to how Handlebars provide, where a for loop on a hbs template, and I can inject data.
Example:
Suppose I have a table like below
But here the row count is dynamic based on data set, how to scale the table dynamically
Note:
I cant create the template in HTML, like handlebars, etc...
Since business people with little to no technical background will be the users who will be generating the PDF template.
You can search the all key values of your JSON, and before insert this value in PdFTable. In my case, i get the lastCellNum:
Row row = rowIterator.next();
PdfPTable table = new PdfPTable(row.getLastCellNum());
Iterator<Cell> cellRow = row.iterator();
while(cellRow.hasNext()) {
Cell cell = cellRow.next();
I am beginner, I have Sheet, which consists of three parts of data.
I want to create separated bar charts, for each part.
It would also be useful, if you add a source, from which I could learn more about creating charts in excel using Java.
How can I create a drop list in excel like drop list in html with the inbuilt "value" like attribute?
My Requirement is: I want to show the description which is not stored in database, but the code for description.
Ex: I have a subject list in an excel cell, for Science the description is "Science", but I want to store the code "SCI" in the Database.
You could use an ActiveX ComboBox in a worksheet, available from the Developers tab.
Enter both columns of data into the worksheet - you can hide the columns. Then set properties of the combobox:
ColumnCount 2
BoundColumn 1
ColumnWidths 0 pt; 20 pt
Set the ListFillRange and LinkedCell.
I understand there used to be issues with distributing workbooks containing ActiveX controls. I am not sure if this is still an issue, particularly when used a common (standard) control.
Of course, Excel is not designed to be a front-end to a database, so you'll need to write all the code to keep everything in-sync.
You could use the simpler Form Control/ComboBox. This will only store the index number in a cell - it does not have any events that you can use. You could use a formula based on the linked cell, that stores the description in another cell. When the user (presumably) clicks a button to submit the data, you would retrieve and store the description from this cell.
Hmm I can see many placeholder occurs all around the web related to java poi... but it seems there is no solution for your question. The only way I found to manage this is to set the cell value with my default text - the first value!
I'm trying to edit a existing PDF file. It is a file where I need to fill in some addresses and other stuff. I want to connect an addressbook to the application so the user can select a user from the addressbook and a part get filled in automatic.
My questions are:
Is it possible to edit a existing PDF file and fill in some fields (+/- 20), because I know there is Itext (http://www.itextpdf.com) but I read that the possiblities are very small.
Or can I better convert the PDF to JPG and get it as background. And create JLabels on the places where I need to fill in the fields. And then print the whole Frame on a A4.
Or are there better posibilities?
So what I need to do, step by step:
Select one of the PDF's (they are in the program)
Fill some fields with content/addresses
Print the PDF/Form with a printer
There is a toolkit given by Adobe named as Acrobat Forms Data Format (FDF) Toolkit which gives API for different languages to fill forms.
You can get the java code at the bottom of that page or check this link
We didn't edit existing PDF's but created totally new letters/reports/doco from our java app using iReport
You could use pdf form and edit field values programmatically using IText or Apache PDFBox (download pdfbox and see SetField.java example)
