ITextSharp: Set table cell border color
提问by Luke101
How do I set the border color of a table cell. here is the code i have:
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);
As you can see i am setting the color two different ways and neither way is working. When the table is rendered the border is always black. How can I fix this.
如您所见，我正在以两种不同的方式设置颜色，但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。

When you set individualcell border properties you either need to set allborder colors and widths individually, or explicitly set the UseVariableBordersproperty to true. Try this example to see what I mean:
当您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，或者将UseVariableBorders属性显式设置为true。试试这个例子看看我的意思：
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);
