Generate Table from Datatable

In this tutorial, we will demonstrate how to generate a table from a DataTable using Aspose.Words for Java. The DataTable is a fundamental data structure that holds tabular data, and with the powerful table processing features of Aspose.Words, we can easily create a well-formatted table in a Word document. Follow the step-by-step guide below to generate a table and integrate it into your word processing application.

Step 1: Set Up Your Development Environment

Before we start, ensure you have the following prerequisites:

• Java Development Kit (JDK) installed on your system.
• Aspose.Words for Java library downloaded and referenced in your project.

Step 2: Prepare Your DataTable

First, you need to prepare your DataTable with the required data. A DataTable is like a virtual table holding rows and columns. Populate it with data that you want to display in the table.

// Create a sample DataTable and add rows and columns
DataTable dataTable = new DataTable(""Employees"");
dataTable.getColumns().add(""ID"", Integer.class);
dataTable.getColumns().add(""Name"", String.class);
dataTable.getRows().add(101, ""John Doe"");
dataTable.getRows().add(102, ""Jane Smith"");
dataTable.getRows().add(103, ""Michael Johnson"");

Step 3: Generate and Format the Table

Now, we will create a new document and generate the table using the data from the DataTable. We will also apply formatting to enhance the appearance of the table.

// Create a new Document
Document doc = new Document();

// Create a Table with the same number of columns as the DataTable
Table table = doc.getFirstSection().getBody().appendTable();
table.ensureMinimum();

// Add the header row with column names
Row headerRow = table.getRows().get(0);
for (DataColumn column : dataTable.getColumns()) {
    Cell cell = headerRow.getCells().add(column.getColumnName());
    cell.getCellFormat().getShading().setBackgroundPatternColor(Color.LIGHT_GRAY);
}

// Add data rows to the table
for (DataRow dataRow : dataTable.getRows()) {
    Row newRow = table.getRows().add();
    for (DataColumn column : dataTable.getColumns()) {
        Cell cell = newRow.getCells().add(dataRow.get(column.getColumnName()).toString());
    }
}

Step 4: Save the Document

Finally, save the document with the generated table to your desired location.

// Save the Document
doc.save(""output.docx"");

By following these steps, you can successfully generate a table from a DataTable and incorporate it into your document processing application using Aspose.Words for Java.
