material-dropdown-select should have floating label or label too.

Thank you for this feature.

minWidth set all columns width is very strange, should in DataColumn2's size set auto or fixed width.

minWidth, smRatio, lmRatio, ColumnSize.M(S,L) are not needed, too complex. only DataColumn2 size set auto or fixed width.

HTML table style and CSS is a good practice, no smRatio, lmRatio, Size.M, Size.S, Size.L

@maxim-saplin , thanks very much, I typed a small piece of very ugly code, the table automatically sets the column width by content, I know there is a performance problem,...

just like the default data_table, build table performance is ok, 0~4ms.   

do not use IntrinsicColumnWidth, calc column max row width by content to set FixedColumnWidth.

In my spare time, I will PR and test.

It's been four years since the WEB UI.
