Struct NumberFormatTable 

pub struct NumberFormatTable {
    pub grouping: Option<String>,
    pub group_separator: Option<String>,
    pub decimal_separator: Option<String>,
    pub floats: Option<bool>,
    pub float_precision: Option<u8>,
    pub exclude_columns: Vec<String>,
    pub unknown: BTreeMap<String, Value>,
}

Long-form number formatting options. Every field is optional; unset fields take their value from the preset named by grouping (or the default).

Fields

grouping: Option<String>

none | thousands | indian | system | any preset name.

group_separator: Option<String>

Character placed between digit groups.

decimal_separator: Option<String>

Character used as the decimal point.

floats: Option<bool>

Whether float columns get grouping too.

float_precision: Option<u8>

Fixed decimal places for floats. Unset keeps Polars’ own rendering.

exclude_columns: Vec<String>

Columns never formatted. Supports * and ? globs.

unknown: BTreeMap<String, Value>

Keys that are not recognised, captured rather than discarded.

A misspelled key here would otherwise be invisible: every field has a default, so the table resolves to “no formatting” — which is also what the default config does. The user would see identical output whether they typo’d the key or never wrote it. Capturing unknown keys lets NumberFormatConfig::resolve name the offending one instead.
