Step to reprocedure:
1 - choose a table, view structure, pick a column and click "Change" to alter this column
2 - Just change column name - click save
3 - We are backed to table structure page, now we want to add new 3 column for example,
enter 3 -- columns from -- at beginning of table -- click go
4 - Enter 3 new column, type int, NULL default value (end allow NULL will automatically checked)
5 - Save -- got error.
