How to add a button to a table cell [message #1854745]

Recently, we encountered a requirement to refactor TableView to NatTable, where the original table contains a column of cells containing buttons, and clicking the button triggers a custom dialog event，as shown in the attached picture.

I want to learn Rendering_cells_as_a_link_and_button in NatTable example, but it treats all cells as a button, and I click it and it doesn't trigger the event, I want to know the right way to do it, hope to get your valuable advice.

Hi,

well the example you are referring to is actually not what you want to do. As the example name says, the whole cell is rendered as a button. And this is not what you want to achieve. From the screenshot you want to add a button inside a cell additionally to the cell content.

For doing this you need to do several things:

Create a cell painter that renders the cell content and a button
Create an action that should be triggered on click on the button
Register the cell painter and a ui binding that triggers the action on click

I have created a small example to show this in more detail, as it seems to be not covered anywhere else yet: ButtonInCellExample

The only downside would be that there are no haptics on click, e.g. a highlight or animation of the button on click. But I am not sure if this is really a requirement for a button inside a cell. Adding such a thing would be a quite huge additional effort IIRC.
