1.Double click table
2.The filter default is "All"("http://jira.cubrid.org/browse/TOOLS-2851)
3.Input some string and Click "All" and "code"(a column),there will be two tick.
4.Click "more" in the filter list.
5.Un-select all the columns and click ok.
There is still two tick before "All" and "code".
So if you select "All" ,all of other columns filter should have the tick.
if you click one or more than one column filter , "All" filter should not have the tick.
