Does not work stably in excess columns

[alibekdas]

Hi,

I have about 90 columns in a table. Since it is made according to the width of the area, 90 columns come together and are not read In addition, sizing is not possible on the width stably.

_recalcPositions: function() {
var that = this,
pos = 0, // make pos = 0;
