Extract tables from document page Leave feedback
GroupDocs.Parser provides the functionality to extract tables from document page by the GetTables(Int32, PageTableAreaOptions) method:
IEnumerable<PageTableArea> GetTables(int pageIndex, PageTableAreaOptions options);
This method returns a collection of PageTableArea object:
| Member | Description |
|---|---|
| Rectangle | The rectangular area that bounds text area. |
| Page | The page information (page index and page size) |
| RowCount | The total number of the table rows. |
| ColumnCount | The total number of the table columns. |
| PageTableAreaCell Item | The table cell by row and column indexes. |
| double GetRowHeight(int) | The the row height. |
| double GetColumnWidth(int) | Returns the column width. |
GetTables(Int32, PageTableAreaOptions) accepts PageTableAreaOptions object that contains TemplateTableLayout object with table layout (see this article for more details).
Here are the steps to extract tables from the document page:
- Instantiate Parser object for the initial document;
- Check if the document supports hyperlink extraction;
- Call GetTables(Int32, PageTableAreaOptions) method with page index and obtain collection of PageTableArea objects;
- Iterate through the collection and print table cells.
The following example shows how to extract tables from the document page:
// Create an instance of Parser class
using (Parser parser = new Parser(filePath))
{
// Check if the document supports table extraction
if (!parser.Features.Tables)
{
Console.WriteLine("Document isn't supports tables extraction.");
return;
}
// Create the layout of tables
TemplateTableLayout layout = new TemplateTableLayout(
new double[] { 50, 95, 275, 415, 485, 545 },
new double[] { 325, 340, 365, 395 });
// Create the options for table extraction
PageTableAreaOptions options = new PageTableAreaOptions(layout);
// Get the document info
IDocumentInfo documentInfo = parser.GetDocumentInfo();
// Check if the document has pages
if (documentInfo.PageCount == 0)
{
Console.WriteLine("Document hasn't pages.");
return;
}
// Iterate over pages
for (int pageIndex = 0; pageIndex < documentInfo.PageCount; pageIndex++)
{
// Print a page number
Console.WriteLine(string.Format("Page {0}/{1}", pageIndex + 1, documentInfo.PageCount));
// Extract tables from the document page
IEnumerable<PageTableArea> tables = parser.GetTables(pageIndex, options);
// Iterate over tables
foreach (PageTableArea t in tables)
{
// Iterate over rows
for (int row = 0; row < t.RowCount; row++)
{
// Iterate over columns
for (int column = 0; column < t.ColumnCount; column++)
{
// Get the table cell
PageTableAreaCell cell = t[row, column];
if (cell != null)
{
// Print the table cell text
Console.Write(cell.Text);
Console.Write(" | ");
}
}
Console.WriteLine();
}
Console.WriteLine();
}
}
}
