用java代码实现一个string的二维数组建立员工表，并进行行列的取值demo

好的，以下是一个简单的 Java 代码，用于创建一个 String 类型的二维数组作为员工表，以及演示如何访问行和列的值：

public class EmployeeTableDemo {
    public static void main(String[] args) {
        // 创建一个 3 行 4 列的员工表
        String[][] employeeTable = {
            {"Alice", "25", "Female", "Sales"},
            {"Bob", "30", "Male", "Engineering"},
            {"Charlie", "40", "Male", "Marketing"}
        };
        
        // 访问第二行第三列的值
        String gender = employeeTable[1][2];
        System.out.println("Gender of employee at row 2, column 3: " + gender);
        
        // 访问第一列所有员工的名字
        for (int i = 0; i < employeeTable.length; i++) {
            String name = employeeTable[i][0];
            System.out.println("Name of employee at row " + (i+1) + ", column 1: " + name);
        }
    }
}

输出结果为：

Gender of employee at row 2, column 3: Male
Name of employee at row 1, column 1: Alice
Name of employee at row 2, column 1: Bob
Name of employee at row 3, column 1: Charlie
