WPF Documents: How to create paragraphs of "underlines" on which you can write answers to questionnaires

Answer 1

I finally found a way to achieve this, thought I would share.

Create the outside table with two rows and two columns like you would expect.

For the underlines, create three different tables, each with only one row and column, with a border applied only to the bottom.

This is how it looks in code:

        for (int i = 1; i < pQuestionSpec.NumberOfLines; i++)
        {
            Table innerT = new Table();
            var col1 = new TableColumn();

            col1.Width = new GridLength(1, GridUnitType.Star);
            innerT.Columns.Add(col1);

            var innerRowGroup = new TableRowGroup();
            var innerRow = new TableRow();

            var cell2 = new TableCell();
            cell2.BorderThickness = new Thickness(0, 0, 0, 1);
            cell2.BorderBrush = Brushes.Black;
            cell2.Blocks.Add(new Paragraph());

            innerRow.Cells.Add(cell2);
            innerRowGroup.Rows.Add(innerRow);

            innerT.RowGroups.Add(innerRowGroup);

            cell.Blocks.Add(innerT);
        }
