两个excelReadExecutor @Override public void execute(List readSheetList, Boolean readAll) { for (ReadSheet readSheet : sheetList) { readSheet = (readSheet, readSheetList, readAll, rkbookHolder().getGlobalConfiguration()); if (readSheet != null) { tSheet(readSheet); parseXmlSource((etNo()), new XlsxRowHandler(analysisContext, stylesTable)); // The last sheet is read eetHolder().notifyAfterAllAnalysed(analysisContext); } } }
