Table in outlook

Click your right mouse button over the column headings and choose 'Customise current view' or click on View>Current View>Customise Current View. You can add extra columns by using the Fields button and can set sorting, grouping and filtering. There are also buttons for setting the fonts and other formatting.

I did not understand your answer. I open task in outlook. There is no column heading, but blank page. I want to create table like I do in the word.

I obviously didn't understand your question! The easiest way is probably to click on the New button to bring up the task window, click in the large notes area at the bottom then click on the Insert drop down menu within that window and choose Object. Choose Microsoft Word Document and click OK. A table menu now appears, click on this and choose Table and then Insert Table as you would in Word. If you click off the inserted document and can't get your cursor in the table to edit it, double-click it and you should be able to edit it again.
