PropertyTemplate is new for 3.15. It is in package org.apache.poi.ss.util Here are the javadocs: https://poi.apache.org/apidocs/index.html?org/apache/poi/ss/util/PropertyTemplate.html
Both PropertyTemplate and setCellStyleProperties() will help in reducing the number of styles generated. But neither will reduce the number of fills or boarders that are defined. That issue is deeper in the API. However, I have not seen nearly the number of boarders and fills defined as I have styles from using setCellStyleProperty(). You are right, the HashMap does not have all the CellStyle properties in it, just the ones you are trying to change. It uses a putAll() behind the scenes which does a merge with the existing cell's style. -----Original Message----- From: Eric Douglas [mailto:edoug...@blockhouse.com] Sent: Tuesday, December 20, 2016 10:23 AM To: POI Users List <user@poi.apache.org> Subject: Re: How do you code cell striping? Yeah that doesn't work. I wrote a test program that generates a .xlsx file and the borders section looks like this: <borders count="1"><border><left/><right/><top/><bottom/><diagonal/></border></borders> I change nothing except for adding this default border method: BorderStyle DEFAULTBORDER = BorderStyle.HAIR; Map<String, Object> properties = new HashMap<String, Object>(); // border around a cell properties.put(CellUtil.BORDER_TOP, DEFAULTBORDER); properties.put(CellUtil.BORDER_BOTTOM, DEFAULTBORDER); properties.put(CellUtil.BORDER_LEFT, DEFAULTBORDER); properties.put(CellUtil.BORDER_RIGHT, DEFAULTBORDER); // Give it a color (AUTOMATIC) properties.put(CellUtil.TOP_BORDER_COLOR, IndexedColors.AUTOMATIC.getIndex()); properties.put(CellUtil.BOTTOM_BORDER_COLOR, IndexedColors.AUTOMATIC.getIndex()); properties.put(CellUtil.LEFT_BORDER_COLOR, IndexedColors.AUTOMATIC.getIndex()); properties.put(CellUtil.RIGHT_BORDER_COLOR, IndexedColors.AUTOMATIC.getIndex()); Then the call to that util under my cell: r = curSheet.createRow(1); c = r.createCell(0); CellUtil.setCellStyleProperties(c, properties); Then the borders section looks like this: <borders count="9"><border><left/><right/><top/><bottom/><diagonal/></border><border><bottom style="hair"/></border><border><left style="hair"/><bottom style="hair"/></border><border><left style="hair"/><right style="hair"/><bottom style="hair"/></border><border><left style="hair"/><right style="hair"/><top style="hair"/><bottom style="hair"/></border><border><left style="hair"/><right style="hair"/><top style="hair"/><bottom style="hair"><color indexed="64"/></bottom></border><border><left style="hair"><color indexed="64"/></left><right style="hair"/><top style="hair"/><bottom style="hair"><color indexed="64"/></bottom></border><border><left style="hair"><color indexed="64"/></left><right style="hair"><color indexed="64"/></right><top style="hair"/><bottom style="hair"><color indexed="64"/></bottom></border><border><left style="hair"><color indexed="64"/></left><right style="hair"><color indexed="64"/></right><top style="hair"><color indexed="64"/></top><bottom style="hair"><color indexed="64"/></bottom></border></borders> That method example also creates a new HashMap, so it's not pulling sheet defaults. The font on that cell is different from the other cells. The next method described on that page references a PropertyTemplate. I Googled that and found org.apache.poi.ss.util.PropertyTemplate, searched that and found POI 3.9. Whatever that was appears to be gone in POI 3.15.
