Embedding Google Sheets - 1

This embedded spreadsheet 

• is resizable (in edit mode) using grab handles

• is scrollable, but does not respect frozen rows/columns

• includes a 'pop-out' button

• shows the spreadsheet name

• shows sheetname tabs

• When published, the sheet is display only even to those with edit access. The data cannot be edited unless the spreadsheet is 'popped out'

This spreadsheet is embedded using the Insert 'From Drive' option. There are limited formatting options. ie You can select which tab to display and that's it.

Note that using the Embed 'by URL' option with the URL of the spreadsheet gives identical results.

This embedded spreadsheet 

• Has no popout button

• data is editable (if you have edit access)

• is scrollable, and respects frozen rows/columns

This is the same spreadsheet as above embedded using Embed 'Embed code' without parameters:
Goto the spreadsheet, click on the 'Share' button and Copy Link

Then add this link into the embed code box using an iframe tag in the form: 
<iframe height="hhh" width="www%" link </iframe>

The example shown here was done using:
<iframe height="400" width="100%" src="https://docs.google.com/spreadsheets/d/1sqLhj7oWGPEU7vjm-SfD55jqJEi0h47CPeDcILtDUVE/edit?usp=sharing"></iframe>

However, as can be seen, the result is a bit 'busy' as it shows the top menu and edit tools etc.

There is a subpage to this page showing some of what can be done to change what is displayed using various parameters
