# Table View
|
|
|
|
This control supports viewing and editing tabular data. It provides a view of a [System.DataTable](https://docs.microsoft.com/en-us/dotnet/api/system.data.datatable?view=net-5.0).
|
|
|
|
System.DataTable is a core class of .net standard and can be created very easily
|
|
|
|
[TableView API Reference](~/api/Terminal.Gui/Terminal.Gui.TableView.yml)
|
|
|
|
## Csv Example
|
|
|
|
You can create a DataTable from a CSV file by creating a new instance and adding columns and rows as you read them. For a robust solution however you might want to look into a CSV parser library that deals with escaping, multi line rows etc.
|
|
|
|
```csharp
|
|
var dt = new DataTable();
|
|
var lines = File.ReadAllLines(filename);
|
|
|
|
foreach(var h in lines[0].Split(',')){
|
|
dt.Columns.Add(h);
|
|
}
|
|
|
|
foreach(var line in lines.Skip(1)) {
|
|
dt.Rows.Add(line.Split(','));
|
|
}
|
|
```
|
|
|
|
## Database Example
|
|
|
|
All Ado.net database providers (Oracle, MySql, SqlServer etc) support reading data as DataTables for example:
|
|
|
|
```csharp
|
|
var dt = new DataTable();
|
|
|
|
using(var con = new SqlConnection("Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;"))
|
|
{
|
|
con.Open();
|
|
var cmd = new SqlCommand("select * from myTable;",con);
|
|
var adapter = new SqlDataAdapter(cmd);
|
|
|
|
adapter.Fill(dt);
|
|
}
|
|
```
|
|
|
|
## Displaying the table
|
|
|
|
Once you have set up your data table set it in the view:
|
|
|
|
```csharp
|
|
tableView = new TableView () {
|
|
X = 0,
|
|
Y = 0,
|
|
Width = 50,
|
|
Height = 10,
|
|
};
|
|
|
|
tableView.Table = yourDataTable;
|
|
```
