widetable – An en­vi­ron­ment for type­set­ting ta­bles of spec­i­fied width

The pack­age de­fines a new en­vi­ron­ment that, un­like tab­u­larX, type­sets a ta­ble of spec­i­fied width by work­ing on the in­ter-col­umn glue; the tab­u­lar cells will all be stretched (or shrunk) ac­cord­ing to need.
The pack­age will use the e-TeX arith­metic ex­ten­sions if they are avail­able (they are, in most mod­ern dis­tri­bu­tions).
