Table: fixed bug

Table: fixed bug

- fixed insert error
-- error: if new table item has same index as selected item index,
throw index out of bounds exception when copy selection array
-- cause: table item set item index itself before creaetd by table
so items had same index are two...so throw exception
-- solution: table item does not set index itself, only table set item index

- fixed select table item error
-- error: when select table item..you can see parts that not drawing
-- cause: table item and table have different width
if table width has been changed, table item width has not changed..
-- solution: when table width has been changed, also change table item width
