Java insert a table to Word document and set the table format and styles

This article shows how to use Spire.Doc for Java to programmatically insert a table into a word document and set the format and styles for the table.

Installing Spire.doc.jar

If you create a Maven project, you can easily import the jar in your application using the following configurations. For non-Maven projects, download the jar file from this link and manually add it as a dependency in your application.

The following assembly directives are required to compile the code in this topic.

import com.spire.doc.*;
import com.spire.doc.documents.HorizontalAlignment;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.TableRowHeightType;
import com.spire.doc.documents.VerticalAlignment;
import com.spire.doc.fields.TextRange;

With Spire.Doc, we could use the document.addSection().addTable method to add a table into a new word document. And we could use table.applyHorizontalMerge(0,1,3) method to merge the table cells horizontally. Here are the code snippets of how to insert a table to word processing document and set the format of the table.

import com.spire.doc.*;
import com.spire.doc.documents.HorizontalAlignment;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.documents.TableRowHeightType;
import com.spire.doc.documents.VerticalAlignment;
import com.spire.doc.fields.TextRange;

import java.awt.*;

public class addTable {
    public static void main(String[] args) {

        //Create a new document and add a section
        Document document = new Document();
        Section section = document.addSection();

        //define the data for table
        String[] header = {"Table", "Horizontal merge the cells"};
        String[][] data =
                {
                        new String[]{"John", "Male", "Sales", "0109"},
                        new String[]{"Louis", "Female", "Developer", "0111"},
                        new String[]{"Jack", "Male", "Developer", "0110"},
                        new String[]{"Moon", "Male", "Support", "0112"},
                        new String[]{"Vicky", "Female", "Test", "0113"},
                };

       //Add a table
        Table table = section.addTable(true);

        //set the rows and columns for the table
        table.resetCells(6,4);

        //merge the cells horizontally
       table.applyHorizontalMerge(0,1,3);

        //merge the cells vertically
       //table.applyVerticalMerge(2,2,3);

        //Auto fit column widths to window
        table.autoFit(AutoFitBehaviorType.Auto_Fit_To_Window);

        //Set the first row as table header and add data
        TableRow row = table.getRows().get(0);
        row.isHeader(true);
        row.setHeight(40);
        row.setHeightType(TableRowHeightType.Exactly);
        row.getRowFormat().setBackColor(Color.gray);
        for (int i = 0; i < header.length; i++) {
            row.getCells().get(i).getCellFormat().setVerticalAlignment(VerticalAlignment.Middle);
            Paragraph p = row.getCells().get(i).addParagraph();
            p.getFormat().setHorizontalAlignment(HorizontalAlignment.Center);
            TextRange range1 = p.appendText(header[i]);
            range1.getCharacterFormat().setFontName("Arial");
            range1.getCharacterFormat().setFontSize(14f);
            range1.getCharacterFormat().setBold(false);
        }

        //add data to the rest of rows
        for (int r = 0; r < data.length; r++) {
            TableRow dataRow = table.getRows().get(r + 1);
            dataRow.setHeight(25);
            dataRow.setHeightType(TableRowHeightType.Exactly);
            dataRow.getRowFormat().setBackColor(Color.white);
            for (int c = 0; c < data[r].length; c++) {
                dataRow.getCells().get(c).getCellFormat().setVerticalAlignment(VerticalAlignment.Middle);
                TextRange range2 = dataRow.getCells().get(c).addParagraph().appendText(data[r][c]);
                range2.getCharacterFormat().setFontName("Arial");
                range2.getCharacterFormat().setFontSize(10f);
            }
        }

        //Set background color for cells
        for (int j = 1; j < table.getRows().getCount(); j++) {
            if (j % 2 == 0) {
                TableRow row2 = table.getRows().get(j);
                for (int f = 0; f < row2.getCells().getCount(); f++) {
                    row2.getCells().get(f).getCellFormat().setBackColor(new Color(173, 216, 230));
                }
            }
        }
        //Save the document
        document.saveToFile("CreateTable.docx", FileFormat.Docx_2013);
    }
}

Once the code is executed successfully, we will get a Word document with table like this:
