Group

Struct Group 

Source
pub struct Group {
    pub expression: String,
    pub descending: bool,
    pub header: Option<Band>,
    pub footer: Option<Band>,
    pub repeat_header: bool,
    pub page_break_before: bool,
}
Expand description

A grouping level with its header and footer.

Fields§

§expression: String

Rows with the same value of this expression form a group.

§descending: bool

Groups in descending order.

§header: Option<Band>

Printed before each group.

§footer: Option<Band>

Printed after each group; aggregates in it cover the group.

§repeat_header: bool

Prints the header again at the top of each page the group continues on.

§page_break_before: bool

Starts each group (after the first) on a new page.
