JXLS-为空白单元格添加公式，公式会消失
[英]JXLS - add formula for blank cells, formula just disappears
问题描述
I created a report with JXLS and an excel template. 
我用JXLS和一个excel模板创建了一个报告。 I have a bunch of cells/columns pulling data from my database, then I have a few columns that are blank, and then I have some formulas/conditionals in a few columns in my report as well. 我有一堆单元格/列从数据库中提取数据，然后有几列为空白，然后在报告的几列中也有一些公式/条件。 The issue I am having is that one of the formulas, needs to run/ multiply two blank columns (someone will download the report and input the numbers manually in those blank columns), and when I run the generate the report through my Java app, the column with the formula comes up as =0. 我遇到的问题是其中一个公式需要运行/乘以两个空白列（有人将下载报告并在这些空白列中手动输入数字），并且当我通过Java应用运行生成报告时，具有公式的列显示为= 0。 Anyways to get the formula to stick, so the people manually entering the numbers in the blank columns do not have to add/input the formula themselves? 无论如何，要使公式保持不变，因此人们在空白栏中手动输入数字就不必自己添加/输入公式了吗？

You should get Jxls to process AC and AD cells by putting a dummy JEXL expression in there. 您应该通过在其中放置虚拟JEXL表达式来使Jxls处理AC和AD单元。
The simplest way is to put ${null} into AC and AD cells in your template. 最简单的方法是将${null}放入模板的AC和AD单元中。
