easytable

This is a small project that builds upon Apache's PDFBox (>= 3.0.0) and should allow you to create tables in a fairly simple way. It emerged from the need in another project. Therefore, it also may miss some crucial features. Nevertheless, there is:

setting font and font size, table, row, column and cell level
line breaking and line spacing
background color and style on table, row, column and cell level
padding (top, bottom, left, right) on table, row and cell level
border color, width and style (on table, row or cell level)
support for text alignment (right, left, center, justified)
vertical text alignment (top, middle, bottom)
column spanning and row spanning
images in cells
allowing for a lot of customizations
experimental: vertical text, drawing a large table's overflow on the same page

One can also override classes that are responsible for table/cell drawing, i.e. their drawing behaviour can be customized to a pretty high extent.

It is also possible to draw a table over multiple pages (even with the header row being repeated on every new page) or to draw a large table's overflow next to the already existing table on the same page (see below for examples).

Installation

Add this to your pom.xml:

<dependency>
    <groupId>com.github.vandeseer</groupId>
    <artifactId>easytable</artifactId>
    <version>1.0.2</version>
</dependency>

Or checkout the repository and install it locally with maven (e.g. for thedevelop branch):

mvn clean install -DskipTests -Dgpg.skip -Ddependency-check.skip=true

Examples

There is a minimal full working example which should help you to get started.

For a bit more involved tables have a look at this code which is needed for creating a PDF document with the following two tables:

For the next example have a look at the SettingsTest.java:

The last one illustrates the use of vertical text in text cells. The code for it can be found here:

Drawing the overflow of a large table on the same page is also possible:

If you run the tests with mvn clean test there also some PDF documents created which you can find in the target folder. The corresponding sources (in order to understand how to use the code) can be found in the test package.

Kudos

to Binghammer for implementing cell coloring and text center alignment
to Sebastian Göhring for finding and fixing a bug (column spanning)
to AndreKoepke for the line breaking feature, some bigger nice refactorings and improvements
to Wolfgang Apolinarski for the printing over pages and bugfixes
to AdrianMiska for finding and fixing an issue with cell height
to TheRealSourceSeeker for finding a bug caused by using floats
to Drummond Dawson for code changes that allowed removing a dependency
to styssi for allowing several multipage tables being drawn on the same page
to Richard Mealing for adding the license section to the pom.xml
to msww for finding a small issue
to VakhoQ for implementing border styles
to Miloš Čadek for implementing alignment of vertical text cells
to Chemmic for adding repeating headers to tables that overflow on the same page

Q&A

Can I use the library with version PDFBox 2.x.x?

Every version of easytable < 1.0.0 is built on PDFBox 2.x.x.

Note that easytable 1.0.0 and below do basically only differ in the support PDFBox version, but not in their feature set. Only exception being the experimental support for paragraph cells which had to be dropped with the upgrade to PDFBox 3.

Also note that easytable >= 1.0.0 is built for Java 11 and higher, whereas lower versions are using Java 8.

Can I customize the drawers for my own specific needs?

Yep, you can customize the cell drawers itself or (depending on your use case) you can just create a custom cell.

For using a customized cell drawer, have a look at CustomCellDrawerTest.

In case you want to create your own type of cell (which shouldn't really be necessary since the drawing can be completely adapted) you will need to use Lombok's @SuperBuilder annotation. Again, just have a look at the code: CustomCellWithCustomDrawerUsingLombokTest

Can I draw a table over multiple pages?

Yes, have a look at TableOverSeveralPagesTest.java. Just use startY(...) and endY(..) in order to restrict the vertical part of the page where the table should be drawn:

RepeatedHeaderTableDrawer.builder()
    .table(createTable())
    .startX(50)
    .startY(100F)
    .endY(50F) // <-- If the table is bigger, a new page is started
    .build()

Is there a way to repeat the header on every page?

Depending on whether you want to repeat the header row or not you should use RepeatedHeaderTableDrawer or TableDrawer respectively.

Can I get the `y` coordinate of the end of a drawn table?

Yes. Just use the .getFinalY() method. Also see FinalYTest.java.

Cool, I like it, can I buy you a beer?

Yes. Or you can upvote this answer on stackoverflow. Or:
