Assign a new value to a specified column in a table
Which function can be used to assign a new value to a specified column? Take an example: I have a table names t. If I query a element in row1 and column0, I can invoke t.cell(1, 0). But seems it doesn't support the operation t.cell(1, 0)=2. How to assign 2 to t.cell(1, 0)?
