Format a column (Blue/Bold) if another column contains a value

How do I Format a column (Blue/Bold) if another column contains a value?

Technically, this would just in the current row. Not formatting the entire column.

Hey, You question is not clear, Request you to explain properly what you are trying to achieve, People will have a hard time responding to this

Current
ColA | ColB (default formating)
Text | Text may contain @ sign

Desired
ColA | ColB
Blue/Bold Text for RowColA | when @ sign exists in Row-ColB

IIUC This can be achieved with a JS expression in the table widget plain text column type styling,

The below styles are available under the column styles

Use the JS option to add an expression to control the styles dynamically.

This should resolve your problem
