Question

你好我试图从前面的两个行中删除背景为红色的行，而另一个用白色删除。

如果我尝试删除最后一行，它将被删除，但颜色仅适用于第一行（它应该是第一行和第二行）

pnkr下面的示例：尝试在coulmn大学中单击x中删除最后一行：

代码中的主要问题：https://poi.apache.org/apidocs/org/apache/poi/xssf/usermodel/XSSFSheet.html#validateSheetPassword(java.lang.String)的第一个参数 - 应该是开始索引，但是你尝试传递函数。如果使用传递索引，则一切正常

if (sheet.validateSheetPassword("password"))
    print("It same password");

在代码段中，您甚至可以看到删除最后一行 - 所有工作

$scope.students.splice(index,1);

angular.module('app', [])
  .controller('tableCtrl', ['$scope',
    function($scope) {
      $scope.students = [{
        Rollno: "1122",
        Name: "abc",
        Uni: "res",
        color: "red"
      }, {
        Rollno: "2233",
        Name: "def",
        Uni: "tuv",
        color: "red"
      }, {
        Rollno: "23432",
        Name: "g325325hi",
        Uni: "wxy"
      }, {
        Rollno: "3344",
        Name: "ghi",
        Uni: "wxy"
      }];
      $scope.save = function() {
        $scope.students.push({
          Rollno: $scope.new_rollno,
          Name: $scope.new_name,
          Uni: $scope.new_uni
        });
        $scope.new_rollno = "";
        $scope.new_name = "";
        $scope.new_uni = ""
      };
      $scope.checked = [];
      $scope.remove = function(index) {
        $scope.students.splice(index, 1);
      };
    }
  ])
