cell method
Returns the value at row / column, or null when out of range.
Implementation
Object? cell(int row, String column, {bool ignoreCase = false}) {
final idx = columnIndex(column, ignoreCase: ignoreCase);
if (idx == null || row < 0 || row >= rows.length) {
return null;
}
final values = rows[row];
if (idx >= values.length) {
return null;
}
return values[idx];
}
