[英]Table nested into PDFPCELL in itextsharp
我想給一個桌子提供圓形邊框,但經過研究后我發現它無法完成,但我們可以給一個單元格提供圓形邊框。
所以我做了這樣的事情
PdfPCell cell = new PdfPCell()
{
CellEvent = rr, // rr is RoundRectangle object
Border = PdfPCell.NO_BORDER,
Padding = 4,
Phrase = new Phrase("test")
};
table.AddCell(cell);
document.Add(table);
現在我可以給一個單元格邊框,所以我想要做的是我想將完整的嵌套表放入這個pdfpcell中,以便我可以間接地在該表上實現邊界...
你可以幫忙嗎? 如果你不理解我的方法..問題......我將在評論部分更清楚地解釋......
使用kuujinbo的代碼逐字表示RoundRectangle
類:
public class RoundRectangle : IPdfPCellEvent {
public void CellLayout(
PdfPCell cell, iTextSharp.text.Rectangle rect, PdfContentByte[] canvas
) {
PdfContentByte cb = canvas[PdfPTable.LINECANVAS];
cb.RoundRectangle(
rect.Left,
rect.Bottom,
rect.Width,
rect.Height,
4 // change to adjust how "round" corner is displayed
);
cb.SetLineWidth(1f);
cb.SetCMYKColorStrokeF(0f, 0f, 0f, 1f);
cb.Stroke();
}
}
然后,您只需要一個“外部”和“內部”表,只將CellEvent
放在外部表上。
//Create a one column table
var outerTable = new PdfPTable(1);
//Create a single cell for that outer table
var outerCell = new PdfPCell();
//Turn the border off for that cell because we're manually going to draw one
outerCell.Border = iTextSharp.text.Rectangle.NO_BORDER;
//Bind our custom class for drawing the borders
outerCell.CellEvent = new RoundRectangle();
//Do whatever we want with the inner table
var innerTable = new PdfPTable(3);
for (var i = 0; i < 9; i++) {
innerTable.AddCell("Hello");
}
//When done, add the inner table to the outer cell
outerCell.AddElement(innerTable);
//Add the outer cell to the outer table
outerTable.AddCell(outerCell);
//Add the outer table to the document
doc.Add(outerTable);
