#' @param x Object to be written. For classes supported look at the examples.
#' @param dims Spreadsheet dimensions that will determine `start_col` and `start_row`: "A1", "A1:B2", "A:B"
#' @param start_col A vector specifying the starting column to write to.
#' @param start_row A vector specifying the starting row to write to.

#' @param apply_cell_style Should we write cell styles to the workbook
#' @param remove_cell_style keep the cell style?
#' @param na.strings Value used for replacing `NA` values from `x`. Default
#' `na_strings()` uses the special `#N/A` value within the workbook.
#' @param inline_strings write characters as inline strings
#' @param ... additional arguments
#' @export
#' @details Formulae written using write_formula to a Workbook object will not get picked up by read_xlsx().
#' This is because only the formula is written and left to Excel to evaluate the formula when the file is opened in Excel.
#' The string `"_openxlsx_NA"` is reserved for `openxlsx2`. If the data frame contains this string, the output will be broken.
#' Many base classes are covered, though not all and far from all third-party classes. When data of an unknown class is written, it is handled with `as.character()`.
