Re: how to find style in existing workbook for cell position with
An excellent question. Discovery is partly covered here: http://jakarta.apache.org/poi/getinvolved/index.html Otherwise one can use a combination of org.apache.poi.hssf.dev.BiffViewer foo.xls myfile and possibly engineer files with the low level APIs/stuff to see what is visible when. The Excel 97 dev kit explains this somewhat but I do not recall precedence being directly covered in the way you are looking for in that level of detail.

RE: how to find style in existing workbook for cell position with no cell
Thanks, Levi. After I sent the original message, I realized that BlankRecord probably wouldn't help, because it is set in a cell, and in my case, I don't have a cell (getCell() returns null). I am on the trail of using ColumnInfoRecord, ColumnInfoRecordsAggregate, RowRecord, and others that contain an index to an ExtendedFormatRecord, which seems to compose the essential ingredient of HSSFCellStyle. Finding and accessing these objects is going to be a fair amount of work, however. Has anyone followed this trail before? --Michael -Original Message- From: Levi Strope [mailto:[EMAIL PROTECTED] Sent: Friday, April 27, 2007 11:44 AM To: POI Users List Subject: RE: how to find style in existing workbook for cell position with no cell I believe it can be mapped to a BlankRecord because the cell itself still contains cell formatting. -Original Message- From: Haggerty, Michael [mailto:[EMAIL PROTECTED] Sent: Friday, April 27, 2007 10:28 AM To: poi-user@jakarta.apache.org Subject: how to find style in existing workbook for cell position with no cell When a cell position (some row/column position such as 0,0) in an existing workbook contains a cell, then its style can be found with HSSFCell.getCellStyle().
