Extract tables from document

GroupDocs.Parser provides the functionality to extract tables from documents by the getTables(PageTableAreaOptions) method:

Iterable<PageTableArea> getTables(PageTableAreaOptions options);

This method returns a collection of PageTableArea object:

getRectangleThe rectangular area that bounds text area.
getPageThe page information (page index and page size)
getRowCountThe total number of the table rows.
getColumnCountThe total number of the table columns.
getCell(int, int)The table cell by row and column indexes.
getRowHeight(int)The the row height.
getColumnWidth(int)Returns the column width.

getTables(PageTableAreaOptions) accepts PageTableAreaOption object that contains TemplateTableLayout object with table layout (see this article for more details).

Here are the steps to extract tables from the whole document:

The following example shows how to extract tables from the whole document:

// Create an instance of Parser class
try (Parser parser = new Parser(Constants.SampleInvoicePagesPdf)) {
    // Check if the document supports table extraction
    if (!parser.getFeatures().isTables()) {
        System.out.println("Document isn't supports tables extraction.");
    // Create the layout of tables
    TemplateTableLayout layout = new TemplateTableLayout(
            java.util.Arrays.asList(new Double[]{50.0, 95.0, 275.0, 415.0, 485.0, 545.0}),
            java.util.Arrays.asList(new Double[]{325.0, 340.0, 365.0, 395.0}));
    // Create the options for table extraction
    PageTableAreaOptions options = new PageTableAreaOptions(layout);
    // Extract tables from the document
    Iterable<PageTableArea> tables = parser.getTables(options);
    // Iterate over tables
    for (PageTableArea t : tables) {
        // Iterate over rows
        for (int row = 0; row < t.getRowCount(); row++) {
            // Iterate over columns
            for (int column = 0; column < t.getColumnCount(); column++) {
                // Get the table cell
                PageTableAreaCell cell = t.getCell(row, column);
                if (cell != null) {
                    // Print the table cell text
                    System.out.print(" | ");
