This thread asks how to build a runtime table in a WinForms app rather than creating a DB table. An in-memory System.Data.DataTable used as the DataSource for a DataGridView is a simple, common pattern that keeps the data structure separate from persistent storage. wanted an “ordinary table” for a Windows Form and pointed toward in-memory tables; the snippet below shows a minimal, copy-paste-ready approach plus a few practical notes.

using System;
using System.Data;
using System.Windows.Forms;

public partial class MainForm : Form
{
    public MainForm()
    {
        InitializeComponent();
        Load += MainForm_Load;
    }

    private void MainForm_Load(object sender, EventArgs e)
    {
        var dt = new DataTable();
        dt.Columns.Add("ID", typeof(int));
        dt.Columns.Add("Name", typeof(string));
        dt.Columns.Add("Date", typeof(DateTime));

        dt.Rows.Add(1, "Alice", DateTime.Today);
        dt.Rows.Add(2, "Bob", DateTime.Today.AddDays(-1));

        var dgv = new DataGridView { Dock = DockStyle.Fill, AutoGenerateColumns = true };
        dgv.DataSource = dt;

        Controls.Add(dgv);
    }
}

Place this code after InitializeComponent (for example in Form_Load). When updating from background threads use Invoke/BeginInvoke. For editable but non-bound grids create DataGridViewColumn objects and call dgv.Rows.Add; for purely layout-style cells use TableLayoutPanel. For large datasets consider virtual mode or paging to avoid memory and UI lag. Official references: DataTable class and DataGridView class.

Then search for datatables - they dont need a specific container the principal is exactly the same
