在C#中使用Table进行数据分页通常是通过使用类似于DataGridView或者ListView这样的控件来展示数据,并且结合使用Paging类或者自定义的分页逻辑来实现分页功能。以下是一个简单的示例:

using System;
using System.Windows.Forms;

public partial class Form1 : Form
{
    private DataTable dataTable;
    private int pageSize = 10;
    private int currentPage = 1;

    public Form1()
    {
        InitializeComponent();
        LoadData();
        DisplayData();
    }

    private void LoadData()
    {
        // Load data from database or any other source
        // For demo purpose, we will create a sample DataTable
        dataTable = new DataTable();
        // Add columns to the DataTable
        dataTable.Columns.Add("ID", typeof(int));
        dataTable.Columns.Add("Name", typeof(string));
        // Add rows to the DataTable
        for (int i = 1; i <= 100; i++)
        {
            dataTable.Rows.Add(i, "Name " + i);
        }
    }

    private void DisplayData()
    {
        // Clear existing rows in the DataGridView
        dataGridView1.Rows.Clear();
        // Calculate start and end index of the current page
        int startIndex = (currentPage - 1) * pageSize;
        int endIndex = Math.Min(startIndex + pageSize, dataTable.Rows.Count);
        for (int i = startIndex; i < endIndex; i++)
        {
            // Add a row to the DataGridView for each data row
            DataGridViewRow row = new DataGridViewRow();
            row.CreateCells(dataGridView1, dataTable.Rows[i]["ID"], dataTable.Rows[i]["Name"]);
            dataGridView1.Rows.Add(row);
        }
    }

    private void btnNext_Click(object sender, EventArgs e)
    {
        currentPage++;
        DisplayData();
    }

    private void btnPrevious_Click(object sender, EventArgs e)
    {
        currentPage--;
        DisplayData();
    }
}

在此示例中,我们创建了一个包含ID和Name列的DataTable,并填充了100条数据。然后,我们通过点击“Next”和“Previous”按钮来切换不同页数的数据。您可以根据需要自定义分页逻辑,并根据实际需求调整代码。
