You can use the Data tab in the Properties dialog box to enter data into a table or parts list, and to manipulate the format of the table.
You can define a new column heading and edit an existing column heading by double-clicking the header cell on the Data tab, or by selecting a column and then selecting the Format Column button 
. This displays the Format Column dialog box, where you can customize the format for the selected column. You can do such things as set the column width; create, position, and align a column header; align data; and show and hide columns and headers.
In the Format Column dialog box, you can use the Format Cells button to display the Format Table Cells dialog box.
To learn how you can use the Format Column dialog box and the Format Table Cells dialog box to customize the appearance of the header rows and data cells, see the Help topic, Formatting columns and data cells.
To learn how you can insert or delete columns and rows, move rows, drag columns from one location to another, see the Help topic, Make changes to a table or parts list.
White data cells may be edited. You can double-click a cell to edit it, and press the Tab key to save the value you type.
Gray shaded data cells are disabled for direct editing, because they contain content derived from the model by property text. You can override the derived values in these cells using the following shortcut commands:
Allow Cell Overrides—When you use this command to enter a new value, the cell is no longer associative to the model.
Clear Cell Overrides—This command resets the value of an edited cell to its original value derived by property text.
You can copy and paste cells from a spreadsheet into a user-defined table or into user-defined cells in system-generated tables, such as parts lists and family of parts tables.
When importing a spreadsheet, you need to ensure that the number of columns and rows are exactly the same in the table and spreadsheet or you may lose data during the copy and paste. For example, if your table contains three columns and five rows, but the spreadsheet contains four columns and six rows, the table is not large enough and data will be lost.
