Please see the example below,this is the result I hope to get.
Now,I did it by changing the x value with fixed value.
But I konw, the width of the column could be change when screem size changed.
I want to change x with a dynamic value.
In my mind , first I set the datalable in right side of colunm.
When I get the width of column, change it to a negative value, and set this negative value to x of datalable,then datalable can move to the correct position.
Can anyone tell me how to implement it , or there are other ways
