ITextSharp:设置表格单元格边框颜色

Question

如何设置表格单元格的边框颜色.这是我的代码:

// create and define table
var table = new PdfPTable(8);
table.HorizontalAlignment = Element.ALIGN_CENTER;

//table.HeaderRows = 1;

// the cell object
PdfPCell cell;
var f = FontFactory.GetFont("Tahoma", 11, Font.BOLD);

cell = new PdfPCell(new Phrase("Source Review", f));
cell.BorderColorLeft = new BaseColor(255, 255, 255);
cell.BorderColorRight = new iTextSharp.text.BaseColor(255, 255, 255);
table.AddCell(cell);

正如你所看到的,我正在以两种不同的方式设置颜色,两种方式都不起作用.渲染表格时,边框始终为黑色.我怎样才能解决这个问题.

设置单个单元格边框属性时,您需要单独设置所有边框颜色和宽度,或者显式设置UseVariableBorders属性true.试试这个例子来看看我的意思:

PdfPTable table = new PdfPTable(1);
PdfPCell cell = new PdfPCell(new Phrase("test 1"));
cell.UseVariableBorders = true;
cell.BorderColorLeft = BaseColor.BLUE;
cell.BorderColorRight = BaseColor.ORANGE;
table.AddCell(cell);

cell = new PdfPCell(new Phrase("test 2"));
cell.BorderColorLeft = BaseColor.RED;
cell.BorderColorRight = BaseColor.GREEN;
cell.BorderColorTop = BaseColor.PINK;
cell.BorderColorBottom = BaseColor.YELLOW;
cell.BorderWidthLeft = 1f;
cell.BorderWidthRight = 1f;
cell.BorderWidthTop = 1f;
cell.BorderWidthBottom = 1f;
table.AddCell(cell);

cell = new PdfPCell(new Phrase("test 3"));
cell.BorderColor = BaseColor.GREEN;
table.AddCell(cell);
