pdfptable

问题 I am using iTextSharp version 5.4.5.0. I am trying to print PdfPTable with Multiple PdfPCell. The Number of PdfPCell will be dynamic. So How can I assign width to the dynamically generated PdfPCell ? I know how to assign width to Static and Fixed number of Cell. But for Dynamic cell, how can I assign width to each of the dynamically generated Cells ? The Number of PdfPCell is not fixed. Please help me ? Thanks. 回答1: Even after some back and forth in comments to the original question, I am not

问题 Does iTextPdf allow to set spacing between cells in table? I have a table with 2 columns and I am trying to draw a border-bottom on cell. I want space between each border same as cell padding. I am using below code: PdfPTable table = new PdfPTable(2); table.setTotalWidth(95f); table.setWidths(new float[]{0.5f,0.5f}); table.setHorizontalAlignment(Element.ALIGN_CENTER); Font fontNormal10 = new Font(FontFamily.TIMES_ROMAN, 10, Font.NORMAL); PdfPCell cell = new PdfPCell(new Phrase("Performance",

问题 Update: After some discussion, we decided to go with TeX, specifically the windows compatible MiKTeX. We realised that even if we could get the dynamic lengthed table formatted by micromanaging the layout (which doesn't seem possible or is as tedious as calculating row height for each row), there are other dynamic controls like large text boxes that we would also need to micromanage so we decided to generate the whole doc on the fly. With that in mind, going to TeX was the obvious choice

问题 I'm creating "labels" and textboxes and checkboxes using iTextSharp, but my attempts to derive from that code to create buttons has not yet been successful. Here is how I'm creating textBoxes: PdfPCell cellRequesterNameTextBox = new PdfPCell() { CellEvent = new DynamicTextbox("textBoxRequesterName") }; tblFirstRow.AddCell(cellRequesterNameTextBox); . . . public class DynamicTextbox : IPdfPCellEvent { private string fieldname; public DynamicTextbox(string name) { fieldname = name; } public

问题 I'm using iTextPdf 5.4.1. I have a table with many rows in it, and when the table auto-splits to the next page, I want to insert an Image and then another page break to continue the table's rows. For example: say a table will take up 2 pages based on the number of rows it has. The final output should be: page 1: table rows that fit on first page page 2: image page 3: remaining table rows. So, each time the table splits, i want to insert an image and then a page break. I'm trying to use the

问题 I am creating a table where each column has its own alignment as shown below. How do I accomplish it at column level than at cell level? 回答1: iText and iTextSharp don't support column styles and formatting. The only way to do this is as you are doing currently, cell by cell. EDIT The easiest work around is to create helper methods that set your common properties. These can either be done through extension methods or just regular static methods. I don't have a C# IDE in front of me so my

问题 I'm facing a problem while trying to generate a PdfPTable and calculate its height before adding it to a document. The method calculateHeights of PdfPTable returned the height a lot greater than the height of a page (while the table is about 1/4 of page's height), so I wrote a method to calculate the height: protected Float getVerticalSize() throws DocumentException, ParseException, IOException { float overallHeight=0.0f; for(PdfPRow curRow : this.getPdfObject().getRows()) { float maxHeight =

问题 I'm using ItextSharp to create a PDF document with multiple PdfPTables. I group multiple PdfPTables using a list, and the list is created in a function and returned as a list. I then take the list and loop through it to add each PdfPTable to the document. In the case that the next PdfPTable in the list is larger than the remaining space on the document I want to add a new page. Using a breakpoint, I've noticed that "table.TotalHeight" always returns 0, when I expect it to return a positive

问题 I am currently using iText to generate PDF reports. I want to set a medium size image as a background in PdfPCell instead of using background color. Is this possible? 回答1: You can find an example on how to do this with iText 5.5.1 here. You need to create your own implementation of the PdfPCellEvent interface, for instance: class ImageBackgroundEvent implements PdfPCellEvent { protected Image image; public ImageBackgroundEvent(Image image) { this.image = image; } public void cellLayout
