This example shows how to extract the Compute SUBTOTAL from the sample invoice below.
It first finds the table containing the invoice lines, then finds the table row containing the "Compute" row header, and then
finds the 4th cell (.Children[3]) and picks the Value from cell object.

// PdfTree pdfTree = ...from an "Extract content from PDF as document tree" action

// Find the table element containing a (descendant) cell with the heading (value) "SERVICE".
var serviceDetailsTable = pdfTree.Where(element => element.ElementType == "Table" && element.Descendants().Any(c => c.Value == "SERVICE")).FirstOrDefault();

// Locate the row containing the "Compute" row header.
var computeRow = serviceDetailsTable.Descendants().Where(c => c.Value == "Compute").First().Parent.Parent;

// Pick the value of the element in the 4th (Children[3]) cell (.Children[0]). 
// Remember that the value is not stored in the cell itself, but rather in a nested child element of the cell.
var subtotalComputeText = computeRow.Children[3].Children[0].Value;

// The amount is on the following format: $24.89
var subtotalCompute = double.Parse(subtotalComputeText, NumberStyles.Currency, CultureInfo.CreateSpecificCulture("en-US"));
