Timestamped Scrolling Table

[lvzhou1]

Distinguished colleagues, I need to create a scrolling text box with timestamps, containing three records: a time column and temperature feedback from two devices. The temperature feedback will change over time. My variables are as follows:

PV0 (real-time timestamp): loc://time_tick
script.txt

PV1 (Device 1 temperature): PLC1215C:spi-c1_K

PV2 (Device 2 temperature): PLC1215C:spi-c2_K

Currently, I can confirm that all three PVs are functional. I suspect the issue might be with the script configuration, as the table always displays "Click to add" after running. I would appreciate any advice or solutions. Thank you all.

@lvzhou1, I assume you're using the table widget, right?

[lvzhou1]

Yes, the Table widget is being used.

@lvzhou1, can you please attach your bob file?

[lvzhou1]

Yup.Thank you.

So the zip file contains the bob file with a table widget. The script for that widget is not the same as the one attached previously to this discussion.
Some observations and comments:

1. To avoid rendering "Click to add...", untick "Editable" in the widget properties
2. Running the unedited bob file, the loc://timer_tick is never updated, so it stays at its initial value of zero.
3. If I replace the script with the one attached in this discussion, I get the following the Phoebus error log:
   SyntaxError: ('no viable alternative at input \'"{float(val):.{decimals}f}"\'', ('EmbeddedPy', 29, 16, ' return f"{float(val):.{decimals}f}"\n'))

I'm assuming you want up to 10 rows of the most recent values in the table, correct?

Yes, I've been trying to implement this function, so the script is being updated as well.
