How to change TableView cell color?

[oo777]

Working with v1 recently and I need a way to render the text within a cell in a different color depending on its value. Any help appreciated!

You want to use ColorGetter on ColumnStyle

Here is an example:

using System.Data;
using Terminal.Gui;

namespace Test
{
    public class Program
    {
        static void Main()
        {
            Application.Init();
            var w = new Window() { Title = "My Window" };

            var tv = new TableView
            {
                Width = Dim.Fill(),
                Height = Dim.Fill(),

            };
            var dt = new DataTable();
            var col = dt.Columns.Add("fish");
            dt.Rows.Add("A");
            dt.Rows.Add("B");
            dt.Rows.Add("C");

            tv.Table = dt;

            var pink = CreateScheme(Color.BrightMagenta);
            var normal = CreateScheme(Color.White);

            var colStyle = tv.Style.GetOrCreateColumnStyle(col);
            colStyle.ColorGetter = (e) =>
            {
                return e.CellValue == "B" ? pink : normal;
            };

            w.Add(tv);
            Application.Run(w);
            Application.Shutdown();
            
            return;
        }

        private static ColorScheme CreateScheme(Color foreground)
        {
            return new ColorScheme
            {
                Normal = new Terminal.Gui.Attribute(foreground, Color.Blue),

                // flip color for selected nodes
                Focus = new Terminal.Gui.Attribute(Color.Blue, foreground),
                HotNormal = new Terminal.Gui.Attribute(foreground, Color.Blue),
                HotFocus = new Terminal.Gui.Attribute(Color.Blue, foreground),
                Disabled = new Terminal.Gui.Attribute(foreground, Color.Blue),

            };
        }
    }
}
