实现思路
1.首先定位到自定义变量名 2.然后先清除自定义变量名#xff0c;可利用setText(null,0)来清除 3.在自定义变量名的位置添加图片#xff0c;使用下面的代码 4.对于图片布局有要求的#xff0c;利用C…apache poi_5.2.5 实现对表格单元格的自定义变量名进行图片替换
实现思路
1.首先定位到自定义变量名 2.然后先清除自定义变量名可利用setText(null,0)来清除 3.在自定义变量名的位置添加图片使用下面的代码 4.对于图片布局有要求的利用CTAnchor进行实现 addNewWrapNone;//根据setBehindDoc来确定浮于文字上方还是下方 addNewWrapSquare;//四周型布局 【注默认是嵌入型文字会遮挡部分图片。】
