How to remove a user-defined text from all columns or all column names?
For example, I have a table: 1. All column names contain "CHA/", how could I remove it quickly and leave it like "Temp""Pressure" and "Flow"? In the real case, I have hundreds of columns containing "CHA/".2. How could I make the first row as the column names? 3. Is there any way to remove "CHA/" from all the cells in the table? Thank you!
