code: public AsciiTable setPaddingLeftRight(int paddingLeft, int paddingRight){
  		for(AT_Row row : this.rows){
  			if(row.getType()==TableRowType.CONTENT){
  				row.setPaddingLeftRight(paddingLeft, paddingRight);
  			}
  		}
  		return this;
  	}
docs: Sets left and right padding for all cells in the table (only if both values are not smaller than 0).
  @param paddingLeft new left padding, ignored if smaller than 0
  @param paddingRight new right padding, ignored if smaller than 0
  @return this to allow chaining
