Hi there, I am trying to build similar to https://github.com/InQBarna/TableFixHeaders lib for compose. I have implemented some parts of it with the help of lazyColumn and lazyRow however the horizontal scroll that scrolls the entire content with top headers lags.I want a smooth scroll. Can anyone guide me in the right direction? check out my implementation here with function DrawTableUi https://github.com/youranshul/tableFixheaderCompose/blob/main/app/src/main/java/com/retroent/tablefixheadercompose/drawTableVIew.kt

Are you testing release builds with r8 enabled?

[Petr Laštovička]

Have you tried LazyGrid?

[Anshulupadhyay03]

@Colton Idle No i am testing on debug build.

[Anshulupadhyay03]

@Petr Laštovička I have not tried with Lazy grid as my problem is not laying out the view but their scroll. Do you really think lazygrid would help?

[Petr Laštovička]

Idk, it just seems like the right tool to do the job

I have forgotten we have only directional grids 😅

Still I would try VerticalGrid with horizontalScroll modifier

[Anshulupadhyay03]

@Petr Laštovička would try with verticalGrid,thanks.

by doing xxx.toList, you are introducing a lot of recompositions. Try to improve that and see if it betters

Please lookup any convos in this slack channel regarding compose perf. pretty much the first thing the compose team will tell you is to test in release builds with minify = true.

@Colton Idle I tried with release builds with minify=true but that did not help, however @myanmarking pointing about the recomposition due to xxx.toList() , I fixed that and it did not work but I realized my ListState.firstVisibleItemScrollOffset was causing lots of recomposition. I have found another approach for a workaround though I have some other problems. I will fix a few things and update you guys on the progress and help. Thanks
