在使用时 行和列一起合并的时候出现索引无法找到问题 所以现在无法进行行列一起合并 只能单独合并
一定要正确定义TableDto 使用CL和RL可进行合并,但不能同时使用 每一列都是固定的 例如
list集合里有7条数据 其中有一条数据进行了合并占用了两格
所以有8列数据 那么以下所有的数据都最多只能占用8列,超出将会报错
如果要上传图片的话 使用以下方法 将图片放置在单元格中
var image = document.AddImage(@"D:/其他文件/图片/" + @"logo.png");
// Create a picture from image.
var picture = image.CreatePicture(25, 100);
table1.Rows[i].Cells[a].Paragraphs[0].AppendPicture(picture);//第一张图
table1.Rows[i].Cells[a].Paragraphs[0].AppendPicture(picture);//第二张图
table1.Rows[i].Cells[a].Paragraphs[0].AppendPicture(picture);//第三张图
//当前图片都放置在同一单元格中

文档太少,例子太少,只有一步一步的试每个方法.最开始用的NPOI
但是NPOI文档都找不到了,合并列还行,到合并行的时候就没办法了,按照其他博客进行操作,太复杂,也没有解释属性和方法的意思,造成即使写了出现错误也不知道为什么会出现这个问题.
Docx虽然文档也没有找到 但是靠猜方法找到了合并行和列的方法 解决了我的问题
