….the tricks that you zip through on autopilot when setting up a datagrid? I’m stuck on how to get column sizing looking elegant….Appreciate any tips up sleeves.
The ones I do on every grid now:
- Fixed width for the boring columns, flex for the one that carries text. IDs, dates, status badges and action buttons get a fixed width that fits their content. The name/description column gets flex so it soaks up whatever space is left. That alone fixes most of the “uneven” look.
- Min width on the flex column. Otherwise it collapses to nothing on smaller screens. Something like 200px, then let the grid scroll horizontally below that instead of squashing everything.
- Custom column type for anything that isn’t plain text. Badges, avatars, buttons. You get a real container in the cell, so padding, alignment and truncation are under your control.
- Truncate instead of wrap. In custom cells, set the text to a single line with ellipsis and put the full value in a tooltip or a detail popup. Rows stay one height and the grid reads much cleaner.
- Right-align numbers and amounts, left-align text, center only icons. Small thing, big difference.
- Height mode Auto for short lists, Fixed for long ones. Fixed is what makes the header sticky, so only use it when you actually want the internal scroll.
- Turn off resizing and column moving unless users really need it. Fewer handles in the header, less visual noise.
Do columns first on desktop, then check the tablet breakpoint and hide the least important columns there rather than trying to fit all of them.
The @stackshortlist is giving you the correct instructions so that you can improve performance and visibility.
Now, if you want to modify the DataGrid visually, it’s a bit more complicated, as it’s a native element and there aren’t many ways to do so other than using the styles shown in the panel. To go into more detail, I recommend:
-
If you want to continue using the DataGrid element: use an HTML element on your page and, within it, place a
<style>and</style>tag so that you can modify the internal attributes of the DataGrid that the panel does not allow you to change. Here’s an example:It can be set to 100% hidden using the `display` property
In this case, I simply removed the outer border from Weweb’s native DataGrid:
-
If you have access to MCP, create your own version of the DataGrid using native components or custom code if you plan to reuse it in other projects. This makes all customisation much easier and allows you to manage it as you see fit. (I do this very often when the DataGrid doesn’t match the design a client requires.) Here’s another example:
This one is created entirely using WeWeb’s native components and implemented as a component with properties.
I hope all this information helps you.
