How can I hide some columns in a QGIS table while I am working on it so that I don't need to scroll so far to the left or right when I have a large number of attributes? Something like Excel does for spreadsheets.
In the attribute table, right click on the column name, then press
Using QGIS 2.14, please select your layer and right-click your mouse, open Properties. On Layer Properties window, push Text Edit button of your target field, under Edit Widget.
By selecting Hidden, your column will be invisible.
NOTE: Please do not Hide your column if you are using other Widget function, such as Value Map. When you set "Hidden", your Value Map setting will be erased...
