To color date columns in a Grafana table, you can use the data transformation feature and apply conditional formatting using CSS. Here's an example of how you can achieve it:

  1. In your Grafana dashboard, select the table visualization panel where you want to color the date columns.
  2. Click on the "Transform" tab to open the data transformation editor.
  3. Add a new transformation by clicking on the "+" button and select "Add field from calculation."
  4. In the Field Calculation section, input a name for the new field, for example, "Formatted Date."
  5. Use the following format to extract and format the date column: date_format({{column_name}},"YYYY-MM-DD") Replace column_name with the actual name of your date column.
  6. Click on the "Add Transformation" button to apply the field calculation.
  7. Go back to the "Fields" tab and locate the new field ("Formatted Date") that you just created.
  8. On the right side of the field, you will find a "Styling" option. Click on it.
  9. In the Styling section, you can add CSS code to define the colors. For example, use the following code to color the date cells based on their value: .table-panel-cell-container:nth-child(4) { background-color: #FF0000; /* Red */ } .table-panel-cell-container:nth-child(5) { background-color: #00FF00; /* Green */ } Adjust the nth-child index and the color values according to the number of date columns and the desired colors.
  10. Click on the "Apply" button to save the styling changes.

Now, the date columns in your Grafana table should be colored according to the provided CSS code.
