Datagrid: "last" option does not stretch last column width

[s-werking]

Describe the bug
When setting the datagrid option stretchColumn to "last", the last column width remains the original calculated value, and does not stretch to the end of the grid.

To Reproduce
Steps to reproduce the behavior:

1. Go to the attached html page
2. Notice that the last column does not stretch to the edge of the datagrid. The other columns have instead stretched larger than their calculated widths.

Expected behavior
When stretchColumn is set to "last" it is expected that all columns except the last column are not stretched and the last column is stretched to the end of the grid.

Can you also post that code change you think might fix? Note that a workaround for this we found investigating is to set stretchColumn: 'lastColumnId' instead of 'last'

[s-werking]

A possible solution for this would be adding something like this inside the 'if' that checks for lastColumn on line 4784 of datagrid.js. It might be an adjusted value from this based on padding and edges :
if (this.settings.stretchColumn === 'last') {
colWidth = diff;
}

Another idea could be if last is set then set it to the last columns ID (which works).

One issue we have noticed with using stretchColumn on the last column, is when resizing the last column past the edge of the datagrid the column is lost and the scrollbar only scrolls to the end of the second-to-last column.
