Java: Create a Table in Word

A table is a common way to present tabular data in a Word document. It helps a lot in organizing a big set of information. In this article, you'll learn how to create how to create a table, fill the table with data, and apply formatting to the table cells using Spire.Doc for Java.

Install Spire.Doc for Java

First of all, you're required to add the Spire.Doc.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Create a Simple Table in Word

The table below lists some of the core classes and methods responsible for creating as well as formatting a table.

Name Description
Table Class Represents a table in a Word document.
TableRow Class Represents a row in a table.
TableCell Class Represents a specific cell in a table.
Section.addTbale() Method Adds a new table to the specified section.
Table.resetCells() Method Resets row number and column number.
Table.getRows() Method Gets the table rows.
TableRow.setHeight() Method Sets the height of the specified row.
TableRow.getCells() Method Returns the cells collection.
TableRow.getFormat() Method Gets the format of the specified row.

The following are the steps to create a simple table in a Word document.

  • Create a Document object, and add a section to it.
  • Prepare the data for the header row and other rows, storing them in a one-dimensional string array and a two-dimensional string array respectively.
  • Add a table to the section using Section.addTable() method.
  • Insert data to the header row, and set the row formatting, including row height, background color, and text alignment.
  • Insert data to the rest of the rows, and apply formatting to these rows.
  • Save the document to another file using Document.saveToFile() method.
