How to fix mouse over text content (wrap text = off) for "Table" visualization?

[flamcnet]

Hi, 

I am using the table visual:

And text wrap option is Off for header and values:

For some columns I can see the entire text like the one below:

And for some columns in the same table, the mouse over text is being cutted and it is also adding the the "...":

If I expand the column I can see the entire data:

Do you know how to fix it?

Thanks,

Flavia

Hi @flamcnet ,

Thank you for reaching out to Microsoft Fabric Community and for sharing the detailed description and screenshots.

Based on what you've described and the visuals you've provided, this behavior appears to be related to how the Power BI Table visual renders content when Wrap text is turned off, especially for fields with certain characteristics like long text, special characters (such as slashes), or potential line breaks.

Even though both Source System(varchar(255) and Control Descriptionvarchar(1000) are text fields, their tooltip behavior differs, which suggests this might not solely depend on the field length. Fields with embedded characters like slashes (/) or invisible line breaks can sometimes be interpreted as multiline text internally, even when wrapping is off. This may result in Power BI truncating the tooltip earlier than expected, even though the full content exists and is visible when the column is expanded.

A couple of workarounds you could try:
1. Clean or simplify the text in Power Query or a calculated column to remove or replace slashes or line breaks. For example:

Text.Replace([Source System], "/", " ")

or in DAX:

Source System Clean = SUBSTITUTE([Source System], "/", " ")

 2. Consider creating a custom tooltip page. This allows you to display the full content on hover using a card or table visual, independent of column width. Just create a new tooltip page, add the field you want, then assign it to the table visual under Format > Tooltip > Type: Report Page. It ensures consistent and complete display for long or complex values.

3. Test shortening the text to a consistent max length (e.g., 255 characters) to observe if the tooltip behavior becomes more consistent across both fields.

Hope this helps. Please reach out for further assistance.

Hi @v-veshwara-msft, thanks A LOT for your detailed analisys of the issue and proposed solution. It really makes more sense now! I will try to review internally if we can fix the data in de data sync process to prevent the special characters, try to add spaces between any eventual concatenation and any other similar cases.

Hi @flamcnet I think you could adjust the column width, as this issue usually happens due to insufficient column width. Make sure the tooltip is enabled so that hovering over the text shows the full content. If it still shows the same issue, you might need to explore custom tooltips, especially if the text is too long to fit within the table column.

Hi @Akash_Varuna , thanks for your answer! The goal is just to make sure the columns have the same behavior: I want to mouse over the cell and see the entire text, withount having to strech the column width.  Since we already have this mouse over capability somehow working nativelly, the last option is to go for a custom tooltip solution. My big question is: why for one column it works and for another column it does not work. In the database "Source System" is varchar(255) and "Control Description" is varchar(1000). Once I figure out this I think I will be able to solve the issue.

Hi @flamcnet It might be because the longer column (varchar(1000)) is getting truncated, preventing the full text from appearing in the tooltip.You will have to explore custom tooltip in your case for your particular requirement
