如您所见,我有一张带有运动边框和背景颜色的表格(第 1 节):
...但是第 3 部分缺少这些剪裁改进,我不知道为什么。
以下是第 1 节的相关代码(应按原样显示):
PdfPTable tblHeadings = new PdfPTable(3);
tblHeadings.WidthPercentage = 100;
tblHeadings.SpacingBefore = 10f;
float[] headingRowWidths = new float[] { 550f, 50f, 400f };
tblHeadings.SetWidths(headingRowWidths);
tblHeadings.HorizontalAlignment = Element.ALIGN_LEFT;
Phrase phrasesec1Heading = new Phrase("Section 1: Payment Information", timesRoman9BoldFont);
PdfPCell cellSec1Heading GetCellForBorderedTable(phrasesec1Heading, Element.ALIGN_LEFT, ucscgold);
tblHeadings.AddCell(cellSec1Heading);
. . .
doc.Add(tblHeadings);
...这里是第 3 节(未按应有的方式显示):
// Section 3
PdfPTable tblSection3 = new PdfPTable(1);
tblSection3.WidthPercentage = 100;
tblSection3.SpacingBefore = 10f;
//tblSection3.HorizontalAlignment = Element.ALIGN_LEFT;
Chunk sec3PayeeStatus = new Chunk("Section 3: Payee Status", timesRoman9BoldFont);
Chunk requiredFields = new Chunk(" * Required Fields", timesRoman9BoldRedFont);
Paragraph parSection3 = new Paragraph();
parSection3.Add(sec3PayeeStatus);
parSection3.Add(requiredFields);
//Phrase phrasesec1Heading = new Phrase("Section 1: Payment Information", timesRoman9BoldFont);
PdfPCell cellSec3Heading = GetCellForBorderedTable(parSection3, Element.ALIGN_LEFT, ucscgold);
tblSection3.AddCell(cellSec3Heading);
doc.Add(parSection3);
我错过了什么或忘记了什么?表格创建和设置的区别在于单元格/列的数量,以及相关的声明(浮点数组)和属性(setWidths())。添加到 PdfPCell 的代码的不同之处在于,第 1 节使用了一个短语(按我想要的方式显示),第 3 节使用了一个段落(没有),但我试过了:
// try using a Phrase instead of a Paragraph
Chunk sec3PayeeStatus = new Chunk("Section 3 PayeeStatus",
timesRoman9BoldFont);
Chunk requiredFields = new Chunk(" * Require Fields",
timesRoman9BoldRedFont);
Phrase phraseSection3 = new Phrase();
phraseSection3.Add(sec3PayeeStatus);
phraseSection3.Add(requiredFields);
PdfPCell cellSec3Heading GetCellForBorderedTable(phraseSection3,
Element.ALIGN_LEFT, ucscgold);
tblSection3.AddCell(cellSec3Heading);
doc.Add(phraseSection3);
...但这并没有更好,实际上更糟,因为“SpacingBefore”似乎没有“采取”
最后(到目前为止),我尝试使用短语而不是块,如下所示:
Phrase sec3PayeeStatus = new Phrase("Section 3: Payee Status", timesRoman9BoldFont);
Phrase requiredFields = new Phrase(" * Required Fields", timesRoman9BoldRedFont);
Paragraph parSection3 = new Paragraph();
parSection3.Add(sec3PayeeStatus);
parSection3.Add(requiredFields);
PdfPCell cellSec3Heading = GetCellForBorderedTable(parSection3, Element.ALIGN_LEFT, ucscgold);
tblSection3.AddCell(cellSec3Heading);
doc.Add(parSection3);
...但这并不比第一次尝试更好、更差或不同(至少我得到了垂直空间,不过,将第 2 节和第 3 节分开)。
我必须做什么才能显示单元格边框和背景颜色?
更新
这是 GetCellForBorderedTable():
private static PdfPCell GetCellForBorderedTable(Phrase phrase, int align, BaseColor color)
{
PdfPCell cell = new PdfPCell(phrase);
cell.HorizontalAlignment = align;
cell.PaddingBottom = 2f;
cell.PaddingTop = 0f;
cell.BackgroundColor = color;
cell.VerticalAlignment = PdfPCell.ALIGN_CENTER;
return cell;
}
