Grid Row Header Width

Questions
1

Is there an option for Grid viewer in JS API that controls the width of the row header (similar to the one that controls the column header height)?

Indeed, the method was getting a row header column was missing. We have just added two methods, GridColumnList.byIndex and GridColumnList.rowHeader; you can use either of them to control the width, just like that:

let view = grok.shell.addTableView(grok.data.demo.demog());

view.grid.columns.byName('age').width = 200;
view.grid.columns.byIndex(4).width = 300;
view.grid.columns.rowHeader.width = 100;

This API will be available on the dev server tomorrow.
