spire.pdf支持添加嵌套表格和图片到pdf表格的单元格，本文将对此做详细介绍。
c#
//创建pdf文档
pdfdocument pdf = new pdfdocument();
//添加一个页面
pdfpagebase page = pdf.pages.add();
//创建一个pdf表格
pdfgrid grid = new pdfgrid();
//添加两行
pdfgridrow row1 = grid.rows.add();
pdfgridrow row2 = grid.rows.add();
//设置表格的单元格内容和边框之间的上边距和下边距
grid.style.cellpadding.top = 5f;
grid.style.cellpadding.bottom = 5f;
//添加两列
grid.columns.add(2);
//设置列宽
grid.columns[0].width = 120f;
grid.columns[1].width = 120f;
//创建另一个需要嵌套的表格
pdfgrid embedgrid = new pdfgrid();
//添加一行
pdfgridrow newrow = embedgrid.rows.add();
//添加两列
embedgrid.columns.add(2);
//设置列宽
embedgrid.columns[0].width = 50f;
embedgrid.columns[1].width = 50f;
sizef imagesize = new sizef(50, 50);
//加载图片
pdfgridcellcontentlist contentlist = new pdfgridcellcontentlist();
pdfgridcellcontent content = new pdfgridcellcontent();
content.image = pdfimage.fromfile(@"doc.png");
content.imagesize = imagesize;
contentlist.list.add(content);
pdfstringformat stringformat = new pdfstringformat(pdftextalignment.center, pdfverticalalignment.middle);
pdftruetypefont font = new pdftruetypefont(new font("arial unicode ms", 11f), true);
//设置嵌套表格的单元格的值和格式
newrow.cells[0].value = "spire.doc";
newrow.cells[0].stringformat = stringformat;
newrow.cells[1].value = contentlist; //将图片添加到嵌套表格的第二个单元格
newrow.cells[1].stringformat = stringformat;
//设置第一个表格的单元格的值和格式
row1.cells[0].value = "客户姓名";
row1.cells[0].stringformat = stringformat;
row1.cells[0].style.font = font;

row1.cells[1].value = "产品";
row1.cells[1].stringformat = stringformat;
row1.cells[1].style.font = font;
row1.cells[1].style.backgroundbrush = pdfbrushes.forestgreen;
row2.cells[0].value = "肖恩";
row2.cells[0].stringformat = stringformat;
row2.cells[0].style.font = font;
row2.cells[1].value = embedgrid; //将嵌套表格添加到第一个表格的第二行第二个单元格
row2.cells[1].stringformat = stringformat;
//将第一个表格画到页面上
grid.draw(page, new pointf(0f, 30f));
