Table Cell

I have LibreOffice and I made a Dada Table.

My Cell can be a lot Wider then they are.

So I know how to Drag the mouse to make the Cell wider.
But I have to do every Cell and they will not look the same.

How can I have LebriOffice make every Cell as wide as it can be all even and fit on the page?

I go into Table the Calumes.
And I can enter numbers by hand.
But I do not know what I would be entering.

So is there a Tab to have LibreOffice do it?

 

When you installed Libre Office, it would also have offered you to install the HELP manual. If you haven't installed that, you need to install it but choose the correct Help file for the version of Libre Office that you have - the current versions are 'Fresh 5.40' or 'Still 5.3.5'. The help manual download is on the same page as the download link for the version of Libre Office that you have.
It has a section on changing the row height or column width of cells when using Libre Office CALC.

 

There is a also a help guide there to Resizing Rows and Columns in a Text Table

 

Try this:

Highlight the column headers in the spreadsheet that you are using. Click on CTRL and hold while you position the mouse over the line between the first two column headers (A & B). When you see the arrow size the first column the size you want, and they should all resize automatically by the same amount. Is this what you are after?
