Struct Columns 

pub struct Columns<'a> {
    pub header: Vec<&'a str>,
    pub rows: Vec<Vec<String>>,
}

Available on crate feature terminal only.

A list printed as borderless aligned columns.

Cells are padded to the widest cell of their column, measured in terminal display columns, and separated by two spaces; the last column is not padded. An empty or missing cell prints as -, and a line break inside a cell as a space. Nothing is truncated: the terminal folds a long line. Labels and cells print as given: the caller passes the labels uppercase, and sanitizes an untrusted cell first with sanitize::text.

Fields

header: Vec<&'a str>

The column labels, printed as the header row unless empty.

rows: Vec<Vec<String>>

The rendered cells of each row, in print order.

Implementations

impl<'a> Columns<'a>

pub fn new(header: impl IntoIterator<Item = &'a str>) -> Self

Builds a list of the given column labels, without rows.

pub fn push(&mut self, row: impl IntoIterator<Item = impl Display>)

Appends a row, rendering its cells.
