如何将ArrayList值排列到html表的行和列中？
我是编程新手，如果我在编程中犯了任何错误，请原谅 下面是我的MySql表，它还有一行“优先级” 我需要将从数组列表获得的上述数据排列到html表的行和列中。我尝试了几种方法，但没有正确对齐 下面是我的Java页面中的arraylist：-如何将ArrayList值排列到html表的行和列中？,html,jsp,arraylist,html-table,Html,Jsp,Arraylist,Html Table,我是编程新手，如果我在编程中犯了任何错误，请原谅 下面是我的MySql表，它还有一行“优先级” 我需要将从数组列表获得的上述数据排列到html表的行和列中。我尝试了几种方法，但没有正确对齐 下面是我的Java页面中的arraylist：- while(rsgsts.next()) { database.add(rsgsts.getString("vehicle_nm")); database.add(rsgsts.getString("re

测试6在最后一次看到后作为附加行打印，当我向arraylist添加“test7、8、9”时，没有打印任何内容。当我尝试使用从数据库返回的实际arraylist时也是如此。我能够获得与您相同的输出，但这不是我需要的确切结果。从arraylist值中，我需要在“Regnumber”、“Status”、“Priority”、“last seen”列下打印“Test 1”、“Test 2”、“Test 3”、“Test 4”respectively@Perdomoff仍然在“Vehicle”列下打印所有内容（请参阅对jsp的编辑。@Perdomoff仍然无法正常工作。请查看我更新的问题：（@Perdomoff我真的很感谢你的努力。但我最初的问题不仅仅是将arrraylist打印到html表中，我自己也能做到。问题是将arraylist值排列成行和列。你可以更接近，但我仍然无法在我的程序中使用此代码。对不起
