QUESTION
I've been doing a test class to create .xlsx files using a simple example I found. I'm not using a Maven project because the project where I'm going to implement it it's not a Maven project.
The problem is that every time I run the test program I get an error saying that there's a class missing. After look for the jar that contains the missing class and implement it, I run the program again and get the same error but missing another different class. I've already added 4 jars to the program, but every time I keep getting different missing classes. Any leads in how to make this work or if there is a more effective way to create .xlsx files using Apache POI or any other API?
Here's the code I used for the test:

, poi-ooxml-4.0.0.jar
, poi-ooxml-schemas-4.1.jar
and ooxml-schemas-1.4

I am trying to insert a table in Excel using Java Apache Poi. But when I am opening the xlsx file it is throwing the following error and I could not solve it:
...ANSWER
Answered 2018-Nov-06 at 17:22There must be at least content in sheet cells for table column names. In your case cells A1:C1
in sheet Architecture
must have content. In former versions of apache poi
this content had must match the table column names. In current version now the setting the cell content updates the table column names.
