Conditional cell background color in datatable

[skynan507]

Is there a way to have a different font color for a single cell within a extended datatable depending on the value in that specific field?

value 0 => normal font color
value 1 => red font color

How does the syntax look like for the column element?

Would be nice to hear from you ...

I think you need do it in your code java.

Hi,

I do have the case, that individual cells of a dataTable have to have a different background color than other cells of this dataTable. Using the 'styleClass' attribute of the 'rich:column' tag I can change the background color of the whole row, but I need to address the individual cell. Using the 'styleClass' attribute of the 'h:ouputText' (as the following)

<rich:column>
 <h:outputText value="12" id="sumOfAllValues" styleClass="#{!t330RowItems.showSpecialField ? 'rich-table-green' : 'rich-table-cell'}"/>
</rich:column>

is to 'late' because than the background color of the span is set but not of the generated 'td'. Is there a way to create cells with individual background colors?

Thanks in advance and kind regards,

Nille

Using the 'styleClass' attribute of the 'rich:column' tag I can change the background color of the whole row, but I need to address the individual cell.

1) not the whole row but whole column
2) and using EL in attribute for individual cell

ready comments above again

Hi,

1) not the whole row but whole column

sorry, I meant 'column'

2) and using EL in attribute for individual cell

What attribute do you mean? For example I want one cell of the whole table to has a different background color. What attribute of which tag should I use? Using the 'styleClass' of the 'column' addresses to many cells and the attribute of the 'h:outputText' just the span inside the cell and not the cell (meaning TD) itself. Could you give me a hint. please?

Kind Regards,

Nille

Hello Nille,

Try this:

<rich:column styleClass="#{!t330RowItems.showSpecialField ? 'rich-table-green' : 'rich-table-cell'}">
 <h:outputText value="12" id="sumOfAllValues" />
</rich:column>

Sorry guys,

I was sure I tried that and thought it would not work. Apparently, I did a mistake somewhere. So it works now, thanks a lot!

Kind Regards,

Nille
