I am facing a issue when try to remove a XSSF Table after creating one.

Here is my test case with manual print out result.

    Create 3 tables on a single sheet.

     [java] Create Table Name: /xl/tables/table1.xml - Content Type:
application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Create Table Name: /xl/tables/table2.xml - Content Type:
application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Create Table Name: /xl/tables/table3.xml - Content Type:
application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml

Delete table2

    [java] Tables before deletion Name: /xl/tables/table1.xml - Content Type:
application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Tables before deletion Name: /xl/tables/table2.xml - Content Type:
application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Tables before deletion Name: /xl/tables/table3.xml - Content Type:
application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml

     [java] Tables after deletion Name: /xl/tables/table1.xml - Content Type:
application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml
     [java] Tables after deletion Name: /xl/tables/table3.xml - Content Type:
application/vnd.openxmlformats-officedocument.spreadsheetml.table+xml

Create a new table table and it throws exception as below
org.apache.poi.openxml4j.exceptions.PartAlreadyExistsException: A part with the
name '/xl/tables/table3.xml' already exists : Packages shall not contain
equivalent part names and package implementers shall neither create nor
recognize packages with equivalent part names. [M1.12]

Looks like it tries to re-use table3.xml which already exists.

When I look into the code, this line.
XSSFSheet line 3971
int tableNumber =
getPackagePart().getPackage().getPartsByContentType(XSSFRelation.TABLE.getContentType()).size()
+ 1;
