Table

A navigable table with fixed rows/columns and cell selections:

Code:

package main

import (
	"strings"

	"github.com/gdamore/tcell/v2"
	"github.com/rivo/tview"
)

func main() {
	app := tview.NewApplication()
	table := tview.NewTable().
		SetBorders(true)
	lorem := strings.Split("Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.

	cols, rows := 10, 40
	word := 0
	for r := 0; r < rows; r++ {
		for c := 0; c < cols; c++ {
			color := tcell.ColorWhite
			if c < 1 || r < 1 {
				color = tcell.ColorYellow
			}
			table.SetCell(r, c,
				tview.NewTableCell(lorem[word]).
					SetTextColor(color).
					SetAlign(tview.AlignCenter))
			word = (word + 1) % len(lorem)
		}
	}
	table.Select(0, 0).SetFixed(1, 1).SetDoneFunc(func(key tcell.Key) {
		if key == tcell.KeyEscape {
			app.Stop()
		}
		if key == tcell.KeyEnter {
			table.SetSelectable(true, true)
		}
	}).SetSelectedFunc(func(row int, column int) {
		table.GetCell(row, column).SetTextColor(tcell.ColorRed)
		table.SetSelectable(false, false)
	})
	if err := app.SetRoot(table, true).SetFocus(table).Run(); err != nil {
		panic(err)
	}
}
