Christmas Bird Count history report system

This function generates one table-column element for each physical table column. For the computation of the detail column count, see Section 28.1, “CbcHist.nPhysCols(): How many physical detail columns will this occupy?”; the total column count is one larger, because of the row-label column. For the styling of each element, see Section 13.11.11, “FO_DETAIL_COL_WIDE”.
