Code
fn main() {
let mut csv = pro_csv::CSV::default();
csv.load("a;b;c;d\na;b;c;d;d;d;d;d;d;d;\n"); // csv.load_from_file("demo.csv") exist
// Debug & Output

// Insert

println!("# Append column");
csv.append_column(String::from("append_column"));
println!("# Correct the size");

// Set
println!("# Set an element");
// Tips: You can set an element out of the current table
// it will append lines/columns until it have the good size
csv.set(0, 0, String::from("SET"));
// Swap
println!("# Swap two lines");
csv.swap_lines(0, 1).unwrap();
println!("# Swap two columns");

println!("# Remove line if exist");
csv.remove_line(0);
println!("# Remove column column if exist");
csv.remove_column(0);
// Save/Write to file
csv.save("demo.csv").unwrap();
