A table can be linked to data in a Microsoft Excel (XLS, .XLSX, or CSV) file. You can link to an entire spreadsheet, individual row, column, cell, or cell range in Excel.
You can bring data from Microsoft Excel into a table in the following three ways:
A table that contains data links displays indicators around linked cells. If you hover your mouse cursor over the data link, information about the data link is displayed.
If a linked spreadsheet has been changed, such as adding a row or column, the table in your drawing can be updated accordingly using the command. Likewise, if a change is made to a table in your drawing, then you can update the linked spreadsheet using the same command.
By default, a data link is locked from editing to prevent undesired changes to the linked spreadsheet. You can lock cells from data changes, format changes, or both. To unlock a data link, click Locking on the Table toolbar.
