So you've added some data to your data model using the 'enter data' button and you've realised you need to add another row, column or possibly remove some data. It might not be immediately apparent how to do this and I suspect some would delete the table and re-enter the correct information. Theres no need to do this as there is an easy way to modify the original data entered. Here's how to do it. 1. Right click on the table you wish to enter and select 'edit query' 2. In the PowerQuery Editor, double click on the first step labelled 'Source' in the Applied Steps section 3. Now you'll see the 'Create Table' window where you can edit the data you originally entered and then click 'ok' when you're done. Thats it!
