请问jacob操作word表格，如何删除表格指定的行

Question

在网上查了很多代码，大部分都是这种写法，但是执行报错，jacob-1.18,   1.17，  1.14版本都试过了，都报同样的错Dispatch rows = Dispatch.get(table, "Rows").toDispatch();
Dispatch row = Dispatch.call(rows, "Item", new Variant(2)).toDispatch();    
Dispatch.call(row, "Delete");
报错如下：2018-06-10 18:14:24 [ERROR] {com.tjsoft.auction.controller.onlineform.maker.SpecialWorkTimeMaker} (Invoke of: Item

Answer 1

public void delRow(int tableIndex, int rowIndex) {
Dispatch tables = Dispatch.get(doc, "Tables").toDispatch();
// 要填充的表格
Dispatch table = Dispatch.call(tables, "Item", new Variant(tableIndex))
.toDispatch();
// 表格的所有行
Dispatch rows = Dispatch.get(table, "Rows").toDispatch();
Object temp1 = Dispatch.get(rows, "Count");
int count = Integer.parseInt(temp1.toString());
if (count > 1 && rowIndex <= count) {
Dispatch row = Dispatch.call(rows, "Item",new Variant(5)).toDispatch();
Dispatch.call(row, "Delete");
}
}参看下这个吧
