### Golang Fyne Framework Table Component Usage Example In the context of using tables within the Fyne framework for developing graphical user interfaces with Go (Golang), a table is an essential widget that allows displaying data in rows and columns format. Below demonstrates how to create and customize a `Table` component. To utilize the `Table` widget effectively, one must define its structure through implementing specific methods required by the interface such as creating cell widgets or determining content based on row and column indices[^1]. #### Basic Implementation of a Table Widget Using Fyne ```go package main import ( "fyne.io/fyne/v2" "fyne.io/fyne/v2/app" "fyne.io/fyne/v2/container" "fyne.io/fyne/v2/widget" ) func main() { myApp := app.New() window := myApp.NewWindow("Fyne Table Demo") tableData := [][]string{ {"John", "Doe"}, {"Jane", "Smith"}, } tableWidget := widget.NewTable( func() (int, int) { return len(tableData), 2 }, // Number of rows and columns. func(id fyne.CanvasObjectID, cell *widget.TableCell) { row, col := id.Row, id.Col cell.Text = tableData[row][col] }, func() fyne.CanvasObject { return widget.NewLabel("") }) window.SetContent(container.NewVBox( widget.NewLabel("Simple Table"), tableWidget, )) window.Resize(fyne.NewSize(300, 400)) window.ShowAndRun() } ``` This code snippet initializes a simple application window containing a basic table populated with static string values arranged into two columns representing first names and last names respectively. The function provided when calling `NewTable()` specifies the number of rows and columns along with logic for populating each cell's text property dynamically according to position within the dataset.
