尝试从Java(POI API)在excel中设置cellvalue时,单元格值未复制到正确的行中
我有两个数组,长度不同,希望能够插入从B3和D3开始向下的数据,它们是v8columnname和v9columnname。我还有两个名为v8tableNames和v9tableNames的表名,它们已经填充了。我的ArrayList是从两个不同的数据库查询的,我计划在VBA中比较这两行,但我已经设置了宏。我只想让行正确对齐,因为代码现在的B列从B3开始,而D列从B行的最后一个索引开始。非常感谢您的帮助尝试从Java(POI API)在excel中设置cellvalue时,单元格值未复制到正确的行中,java,excel,apache-poi,Java,Excel,Apache Poi,我有两个数组,长度不同,希望能够插入从B3和D3开始向下的数据,它们是v8columnname和v9columnname。我还有两个名为v8tableNames和v9tableNames的表名,它们已经填充了。我的ArrayList是从两个不同的数据库查询的,我计划在VBA中比较这两行,但我已经设置了宏。我只想让行正确对齐,因为代码现在的B列从B3开始,而D列从B行的最后一个索引开始。非常感谢您的帮助 ArrayList v8tableNames = new ArrayList(); Array

对于(int i=0;i您需要更新进入v9columns for循环的“行”:
for (int m = 0; m<v9columns.size();m++) {
// Start at row zero and shift to row 3, then increment by m++ on each iteration
row = sheet.createRow(0+m+2);
