Add Details to a Data Table
As you add point, line, and polygon features to a map layer, you can also add details about these features to the layer's data table. The data table functions like a spreadsheet. You can add new columns and rows to the data table as needed. The information you add to the data table can be used to change the style of the layer's symbols, the content that appears in the features' pop-up windows, etc.
- In My Maps, go to the map layer that you want to edit. Click the layer options icon, then select Open Data Table.
- Each point, line, and polygon feature that you've added to the map layer will have a corresponding row in the layer's data table. The data table includes two default columns: name and description. You can add additional columns to the data table to supply more information about the individual features.
- If you want to add a new column, you'll need to add a column name and choose the type of data that the column contains (e.g., text, numeric, yes/no, or date). Then click Add to add the column to your data table.
- Once you've added the new column (e.g., book quote), you can add any relevant information to your data table.
