A DESCRIPTION OF THE PROBLEM :
A swing table is update on his majour axis but it is not update on his minor axis when we remove texte.
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Launch the code.
1-Insert a texte after "Cell11" and remove the texte.
-Put the curso before "TextB" and press "Enter".
2-Put the curso after "Cell11" and press "Enter" to insert a new line in the cell. Remove this new line.
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Launch the code.
When we Insert a texte after "Cell11" or ... or "Cell43", the table layout is update. and when we remove the texte, the table layout is update too.
ACTUAL -
Launch the code.
1-Insert a texte after "Cell11", the table layout is update.
-Remove the texte, the table layout is not update
-Put the curso before "TextB" and press "Enter", the table layout is update.
2-Put the curso after "Cell11" and press "Enter" to insert a new line in the cell. The table layout is update remove this new line, the table layout is also update.
Conclusion : This problem occurs only when removing along the minor axis.
REPRODUCIBILITY :
This bug can be reproduced always.
