feat: improve table row and column deletion logic

[PleBea]

Improve table row and column deletion logic #82

• Prevent deletion of table rows with exactly one nested row
• Prevent deletion of table columns containing a nested table
• This change helps maintain the structure of complex tables
  while still allowing for conditional content removal
