#' @title Balance Statistics for `sbw` Objects
#'
#' @description
#' Generates balance statistics for `sbwcau` objects from \pkg{sbw}.
#'
#' @inheritParams bal.tab
#' @param x an `sbwcau` object; the output of a call to \pkgfun{sbw}{sbw}.
#' @param s.d.denom `character`; how the denominator for standardized mean differences should be calculated, if requested. See [col_w_smd()] for allowable options. Abbreviations allowed. If not specified, `bal.tab()` will figure out which one is best based on the `par` component of the `sbwcau` object: if "att", `"treated"`; if "atc", `"control"`; otherwise `"pooled"`.
#'
#' @returns
#' If clusters are not specified, an object of class `"bal.tab"` containing balance summaries for the `sbwcau` object. See [bal.tab()] for details.
#'
#' If clusters are specified, an object of class `"bal.tab.cluster"` containing balance summaries within each cluster and a summary of balance across clusters. See [`class-bal.tab.cluster`] for details.
#'
#' @details
#' `bal.tab.sbwcau()` generates a list of balance summaries for the `sbwcau` object given, and functions similarly to \pkgfun{sbw}{summarize}.
#'
#' @seealso
#' * [bal.tab()] for details of calculations.
