Is it possible to make column pinning detect column width change and works dynamically?

[dnjsgur0629]

I found that to use expand with columnPinning in #213, I had to assign a large enough value to the size of mrt-row-expand. However, this method has the demerits that the size of mrt-row-expand must become too large as the layers of data become deeper.


In my case I had to assign 140 to the size of mrt-row-expand.

It seems that the size of mrt-row-expand is too big, even when it is not expanded.


If don't assign a size for mrt-row-expand, the columns will automatically widen each time you expand a row. What if column pinning could detect column width changes and works dynamically?
If this is possible, #240 will also be resolved.
