Allow fixed (exact-size) column widths

[githorse]

I can use the column size prop to adjust column sizes relative to each other, and MRT uses some secret sauce to make the table look good at a lot of different screen widths. I was surprised to find out that -- unlike in other grids I've used -- size, minSize, and maxSize are just suggestions, behaving more like a flex-grow than width, and that the actual rendered width is rarely equal to size. But it turns out that this is usually what I want, because it scales well to lots of different screen widths.

But sometimes I really do want a fixed-width column, and as far as I can tell I can't have one. The actions/expand/command columns are an obvious case; I don't want those to grow dynamically, ever. I also frequently design nested table layouts where some columns in the inner grid line up with columns in the outer grid (called aligned grids in AG Grid); I've done this with other grids, but it seems that it's impossible to do in MRT because I can't control the widths precisely enough. In general, the inability to precisely set a column width has been a real frustration.

Flexible relative sizing (what we have now) and fixed widths are both useful. Both MUI Datagrid and AG Grid, for instance, offer both flex and width props on the columns. I don't know of any datagrids besides MRT that don't support (fixed) width.

How about adding a mechanism (perhaps migrating to the flex and width pattern) that allows exact fixed widths?

I also have a need to have very small (only a single letter) columns and can't see how to do that.

I'm attaching a screen shot of a portion of a table. (Rest of the table omitted for privacy issues). But hopefully you get the gist.

Any help or advice from anyone would be greatly appreciated.

That's what the new grid-no-grow layout mode is for

Fantastic. I will try that out. Thank you for the quick response. Sorry it took me so long to get back to this.

... but I don't think grid-no-grow really answers the mail here, since I need to be able to mix exact-width and flexible-width columns in the same grid (as I can with other grid libraries). We still need a column sizing option that actually just fixes the size of a single column.

This continues to be a major frustration and a big reason I'm now shopping for alternatives to MRT.
