pub fn label_prefix(
label: &str,
pad: usize,
error: bool,
theme: &Theme,
) -> Vec<Span<'static>>Expand description
Build the label-column spans for a row. Output:
" <label><*|space><filler>" — two-space left indent, label, then a red
bold * if error is true (else a space), padded so all values line up
at column indent + 2 + pad + 2.
