Show more than 500 rows in grafana table

hi,danie
We update to grafana7,the new features is very awesome.

but there are some questions in table panel:
1.in the past ,i use 【raw document】 to some the field of elasticsearch,but grafana7 can not do this.when i setting raw document,it will show all the field.
2.logs provide this feature,but it can’t show more then 500 rows,i try to setting “size” in panel json,but it can not work, please tell me how to do.

Have a good day
