## Object data
If your data objects are not stored in a `System.Data.DataTable` then you can instead
create a table using `EnumerableTableSource<T>` or implementing your own `ITableSource`
class.
For example to render data for the currently running processes:
```csharp
tableView.Table = new EnumerableTableDataSource<Process> (Process.GetProcesses (),
new Dictionary<string, Func<Process, object>>() {
{ "ID",(p)=>p.Id},
{ "Name",(p)=>p.ProcessName},
{ "Threads",(p)=>p.Threads.Count},
{ "Virtual Memory",(p)=>p.VirtualMemorySize64},
{ "Working Memory",(p)=>p.WorkingSet64},
});
```
## Table Rendering
TableView supports any size of table (limited only by the RAM requirements of `System.DataTable`). You can have
thousands of columns and/or millions of rows if you want. Horizontal and vertical scrolling can be done using
the mouse or keyboard.

TableView uses `ColumnOffset` and `RowOffset` to determine the first visible cell of the `System.DataTable`.
Rendering then continues until the avaialble console space is exhausted. Updating the `ColumnOffset` and
