あなたのSQLクエリは間違っています:

Caused by: android.database.sqlite.SQLiteException: no such column: description (code 1): , while compiling: SELECT id, nom_produit, prix_achat, prix_vente, description FROM produittable ORDER BY nom_produit asc

'produittable' テーブルに列 ' description ' があることを確認してください

あなたのコードによると：

 @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("CREATE TABLE " + TABLE_PRODUIT + " (id INTEGER PRIMARY KEY, nom_produit TEXT NOT NULL, quntité_alerte TEXT NOT NULL, prix_achat TEXT NOT NULL, prix_vente TEXT NOT NULL, description_produit TEXT NOT NULL)");
    }

列「description_produit」を作成しています
