// Create PDF document
PdfDocument doc = new PdfDocument();
// Set margins
PdfUnitConvertor unitCvtr = new PdfUnitConvertor();
PdfMargins margin = new PdfMargins();
margin.setTop(unitCvtr.convertUnits(2.54f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point));
margin.setBottom(margin.getTop());
margin.setLeft(unitCvtr.convertUnits(3.17f, PdfGraphicsUnit.Centimeter, PdfGraphicsUnit.Point));
margin.setRight(margin.getLeft());

// Add a page
PdfPageBase page = doc.getPages().add(PdfPageSize.A4, margin);

// Add table
PdfTable table = new PdfTable();
PdfSolidBrush brush = new PdfSolidBrush(new PdfRGBColor(Color.black));
table.getStyle().setBorderPen(new PdfPen(brush, 0.5f));
table.getStyle().getHeaderStyle().setStringFormat(new PdfStringFormat(PdfTextAlignment.Center));
table.getStyle().setHeaderSource(PdfHeaderSource.Rows);
table.getStyle().setHeaderRowCount(1);
table.getStyle().setShowHeader(true);
table.getStyle().setCellPadding(2);
table.getStyle().setHeaderSource(PdfHeaderSource.Rows);
table.getStyle().setHeaderRowCount(1);
table.getStyle().setShowHeader(true);

// Set header font and style
PdfTrueTypeFont font = new PdfTrueTypeFont(new Font("SimSun", Font.PLAIN, 12));
table.getStyle().getHeaderStyle().setFont(font);
table.getStyle().getHeaderStyle().setBackgroundBrush(PdfBrushes.getCadetBlue());
PdfTrueTypeFont fontBody = new PdfTrueTypeFont(new Font("SimSun", Font.PLAIN, 10));
// Set even row font
table.getStyle().getDefaultStyle().setFont(fontBody);
// Set odd row font
table.getStyle().getAlternateStyle().setFont(fontBody);
// false: distribute by total width proportion, true: use set column width
table.getStyle().isFixWidth(true);

// Define data
String[] data = {"1;2;3;4;5",
        "A1;B1;1,391,190,000;18.2%; ",
        "A1;B1;126,490,000;1.66%; ",
        "A1;B1;65,648,054;0.86%; ",
        "A1;B1;82,665,600;1.08%; ",
        "A1;B1;37,119,000;0.49%; ",
        "A1;B1;327,216,000;4.29%; "
};
String[][] dataSource = new String[data.length][];
for (int i = 0; i < data.length; i++) {
    dataSource[i] = data[i].split("[;]", -1);
}

table.setDataSource(dataSource);
for(int i = 0; i < table.getColumns().getCount(); i++)
{
    PdfColumn column = table.getColumns().get(i);
    column.setWidth(50);
    column.setStringFormat(new PdfStringFormat(PdfTextAlignment.Center, PdfVerticalAlignment.Middle));
}

// Add table to page
table.draw(page, new Point2D.Float(0, 50));

// Save document
doc.saveToFile("addTable.pdf", FileFormat.PDF);
