I tried following approach and it worked.
rename .twb file to .xml
(if your tableau file is twbx then rename this file to .zip . get .twb file from this zip file. )
Open in notepad
search for following text:
change ’16’ to your desired value.
Now rename the .xml back to .twb. Open in tableau.
Though you could add more columns in tableau by changing xml, UI doesn’t look good. As tableau doesn’t support scroll bar on “Rows”
Tableau tabcmd error
tabcmd login -s https://tableauserver.com -t site1 -u username –p password
*** Uncaught exception RuntimeException: javax.net.ssl.SSLHandshakeException:
sun.security.validator.ValidatorException: PKIX path building failed: sun.securi
ty.provider.certpath.SunCertPathBuilderException: unable to find valid certifica
tion path to requested target
When you get this error there are 2 ways of solving:
Solution1: Add tableau weburl to your trusted url’s in IE.
tabcmd login -s https://tableauserver.com -t site1 -u username –p password –no-certcheck
and append –no-certcheck to export commands as well.
when trying to join a table with lat, long values with Shape file follow below steps .
Add below to the query item.
geography::STPointFromText(‘POINT(‘ + CAST([LONG] AS VARCHAR(20)) + ‘ ‘ + CAST([LAT] AS VARCHAR(20)) + ‘)’, 4326) as loca_geo
join should be Intersects
Join to geometry.
Follow below steps:
select Help → Settings and Performance → Start Performance Recordingfrom the Tableau toolbar.
Then right click on the source in the Data toolbar and select ‘Refresh’. This will force Tableau to re-run the query.
Once the query completes, select Help → Settings and Performance → Stop Performance Recording from the Tableau toolbar.
This should result in a new Tableau window opening with a workbook called ‘Tableau — PerformanceRecording’
Right-click anywhere in the bar next to ‘Executing Query’ and select ‘View data’

Below URL gives a very good idea about this
1. select abc
2. go to color and change opacity from 100% to 0%. this would hide text ‘abc’
3. now right click on column next to abc, go to format-> Column Divider-> pane-> none
4. now reduce the size of abc column as minimal as possible. so user wont be able to see it.
Create a new blank column with text ‘ ‘. Drag this column and repeat above steps – 3,4.
Detailed video is also available at youtube.
Use below function
geography::STPointFromText(‘POINT(‘ + CAST(longitude AS VARCHAR(20)) + ‘ ‘ + CAST(latitude AS VARCHAR(20)) + ‘)’, 4326) as geo_location
