Function to_table 

pub fn to_table(
    title: &str,
    culture: &str,
    columns: &[GridColumn],
    rows: &[Vec<Value>],
    query: &GridQuery,
    matched: &[usize],
) -> GridTable

Takes what the grid shows into a table for a file. A column with a format of its own goes as the text it shows, since only that format knows what it means.
