# GT.cols_move() Move one or more columns. Usage ``` python GT.cols_move( columns, after, ) ``` On those occasions where you need to move columns this way or that way, we can make use of the [cols_move()](GT.cols_move.md#great_tables.GT.cols_move) method. While it's true that the movement of columns can be done upstream of **Great Tables**, it is much easier and less error prone to use the method provided here. The movement procedure here takes one or more specified columns (in the `columns` argument) and places them to the right of a different column (the `after` argument). The ordering of the `columns` to be moved is preserved, as is the ordering of all other columns in the table. The columns supplied in `columns` must all exist in the table and none of them can be in the `after` argument. The `after` column must also exist and only one column should be provided here. If you need to place one more or columns at the beginning of the column series, the [cols_move_to_start()](GT.cols_move_to_start.md#great_tables.GT.cols_move_to_start) method should be used. Similarly, if those columns to move should be placed at the end of the column series then use [cols_move_to_end()](GT.cols_move_to_end.md#great_tables.GT.cols_move_to_end). ## Parameters `columns: SelectExpr` The columns to target. Can either be a single column name or a series of column names provided in a list. `after: str` The column after which the `columns` should be placed. This can be any column name that exists in the table. ## Returns `GT` The GT object is returned. This is the same object that the method is called on so that we can facilitate method chaining. ## Examples Let's use the [countrypops](data.countrypops.md#great_tables.data.countrypops) dataset to create a table. We'll choose to position the `population` column after the `country_name` column by using the [cols_move()](GT.cols_move.md#great_tables.GT.cols_move) method. ``` python from great_tables import GT from great_tables.data import countrypops countrypops_mini = countrypops.loc[countrypops["country_name"] == "Japan"][ ["country_name", "year", "population"] ].tail(5) ( GT(countrypops_mini) .cols_move( columns="population", after="country_name" ) ) ``` | country_name | population | year | |--------------|------------|------| | Japan | 126811000 | 2018 | | Japan | 126633000 | 2019 | | Japan | 126261000 | 2020 | | Japan | 125681593 | 2021 | | Japan | 125124989 | 2022 |
