Struct Column 

pub struct Column {

    pub header: Option<Box<dyn Renderable + Send + Sync>>,
    pub footer: Option<Box<dyn Renderable + Send + Sync>>,
    pub header_style: Style,
    pub footer_style: Style,
    pub style: Style,
    pub justify: JustifyMethod,
    pub vertical: VerticalAlignMethod,
    pub overflow: OverflowMethod,
    pub width: Option<usize>,
    pub min_width: Option<usize>,
    pub max_width: Option<usize>,
    pub ratio: Option<usize>,
    pub no_wrap: bool,
    /* private fields */
}

A column definition within a table.

Columns define how data in a particular column should be displayed, including headers, footers, styling, and width constraints.

Note

The justify, vertical, overflow, and no_wrap fields are defined for API compatibility but are not yet fully implemented. They will be applied in a future version. Currently, cell content is rendered with default justification and wrapping.

Fields

header: Option<Box<dyn Renderable + Send + Sync>>

Column header content.

footer: Option<Box<dyn Renderable + Send + Sync>>

Column footer content.

header_style: Style

Style for the header.

footer_style: Style

Style for the footer.

style: Style

Style for column cells.

justify: JustifyMethod

Horizontal alignment for cell content.

vertical: VerticalAlignMethod

Vertical alignment for cell content.

overflow: OverflowMethod

Overflow handling method.

width: Option<usize>

Fixed width (if set, overrides auto-width).

min_width: Option<usize>

Minimum width constraint.

max_width: Option<usize>

Maximum width constraint.

ratio: Option<usize>

Flexible width ratio (for distributing extra space).

no_wrap: bool

Prevent text wrapping in this column.
