I want to enter table of X and Y values then plot them. I don't want to enter brackets and or commas. Can I prepare grid for myself and them fill it with data in Mathematica, like in Excel?

I found Insert -> Table/Matrix, but how to insert rows columns afterwards?

    $\begingroup$ If your data is in excel you can Import it. If you want to enter your data manually, you can use Insert -> Matrix, choose the right dimension. On windows, ctrl+, adds column and ctrl+enter adds row $\endgroup$

Without using the menus, you can do the following :

enter image description here

On Windows :

  • Hit Ctrl + ",". It creates a new cell with a 2 boxes grid inside.
  • Hit Ctrl + "," as many times as you want to add columns
  • Hit Ctrl + Enter to creates new rows
  • Filling : "a" Tab "b" Tab etc...
  • Then evaluate the cell normally (Shift + Enter)
  • You can give a name to your data by typing "myData=" just before the grid.

Moreover, it is often usefull to create programmatically a pre-filled grid:

enter image description here

The code // ToBoxes // (# /. TagBox[x_, ___] :> x &) // RawBoxes is necessary if you want that the evaluation of the grid gives a List of List (I mean the grid generated by the code //ToBoxes...RawBoxes , ie the last grid).
