tableview's Issues

Add ability to sort by column values

Sorting by column values would make the viewer more useful.
This can be implemented by letting the user click on the header cells.
It would be helpful if it were configurable whether this sorts the whole dataset, or just the data that has been read by the app.
Starting off with sorting just what has been read into memory should be OK.

Fix OpenGL error on Windows

When running on Windows 10:

thread 'main' panicked at ...\eframe-0.23.0\src\native\run.rs:756:43:
An OpenGL error occurred: egui_glow requires opengl 2.0+.

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
error: process didn't exit successfully: `target\debug\table_view.exe` (exit code: 101)

Might have to change the back-end to something that works more seamlessly across platforms, like wgpu as suggested here:
emilk/egui#3165

Add schema viewer

Some formats such as Parquet have a schema that describes the data.
It should be possible for users to inspect the schema using the viewer.
This goes beyond only displaying column types in the headers.

Add recent files

Users should be able to see and select N most recently opened file paths.
N = 10 would be a good start.
If the file path entry doesn't lead to a good file path (perhaps file was moved), it should be removed from the history.
